Historic Beer Birthday: William Lassell

June 18, 2018 By Jay Brooks Leave a Comment

Today is the birthday of William Lassell (June 18, 1799–October 5, 1880). He made great contributions to astronomy throughout his life, but that “hobby” was funded by the fortune he made at his Liverpool brewery. He was initially trained as a merchant, and in 1825 started an apparently successful brewery, and one account states that he “married a widow of a wealthy Liverpool brewer gaining at the same time financial independence.” That may have given him the idea. Perhaps because his life was overshadowed by his astronomical pursuits, there’s very little about his brewery I could find.

Here’s his basic biography from his Wikipedia page:

William Lassell was born in Bolton, Lancashire, a town west of Manchester. He was educated first in Bolton then at Rochdale Academy. After the death of his father, he was apprenticed from 1814 to 1821 to a merchant in Liverpool. He then made his fortune as a beer brewer, which enabled him to indulge his interest in astronomy. He built an observatory at his house “Starfield” in West Derby, a suburb of Liverpool. There he had a 24-inch (610 mm) reflector telescope, for which he pioneered the use of an equatorial mount for easy tracking of objects as the Earth rotates. He ground and polished the mirror himself, using equipment he constructed. The observatory was later (1854) moved further out of Liverpool, to Bradstone.

In 1846 Lassell discovered Triton, the largest moon of Neptune, just 17 days after the discovery of Neptune itself by German astronomer Johann Gottfried Galle. In 1848 he independently co-discovered Hyperion, a moon of Saturn. In 1851 he discovered Ariel and Umbriel, two moons of Uranus.

When Queen Victoria visited Liverpool in 1851, Lassell was the only local she specifically requested to meet.

In 1855, he built a 48-inch (1,200 mm) telescope, which he installed in Malta because of the observing conditions that were better than in often-overcast England. On his return to the UK after several years in Malta he moved to Maidenhead and operated his 24-inch (610 mm) telescope in an observatory there. The 48-inch telescope was dismantled and was eventually scrapped.

Lassell was a Fellow of the Royal Astronomical Society (FRAS) from 1839, won the Gold Medal of the Royal Astronomical Society in 1849, and served as its president for two years starting in 1870. He was elected a Fellow of the Royal Society (FRS) in 1849 and won their Royal Medal in 1858. Lassel was also a Fellow of the Royal Society of Literature (FRSL). He was furthermore elected an honorary Fellow of the Royal Society of Edinburgh (HonFRSE) and of the Society of Sciences of Upsala, and received an honorary LL.D. degree from the University of Cambridge in 1874.

Lassell died in Maidenhead in 1880. Upon his death, he left a fortune of £80,000 (roughly equivalent to £7,200,000 in 2015). His telescope was presented to the Royal Observatory in Greenwich.

The crater Lassell on the Moon, a crater on Mars, the asteroid 2636 Lassell and a ring of Neptune are named in his honour.

This account of Lassell is from A Popular History of Astronomy During the Nineteen Century, by Agnes M. Clerke, published in 1885:

Within seventeen days of its identification with the Berlin achromatic, Neptune was found to be attended by a satellite. This discovery was the first notable performance of the celebrated two-foot reflector[224] erected by Mr. Lassell at his suggestively named residence of Starfield, near Liverpool. William Lassell was a brewer by profession, but by inclination an astronomer. Born at Bolton in Lancashire, June 18, 1799, he closed a life of eminent usefulness to science, October 5, 1818, thus spanning with his well-spent years four-fifths of the momentous period which we have undertaken to traverse. At the age of twenty-one, being without the means to purchase, he undertook to construct telescopes, and naturally turned his attention to the reflecting sort, as favouring amateur efforts by the comparative simplicity of its structure. His native ingenuity was remarkable, and was developed by the hourly exigencies of his successive enterprises. Their uniform success encouraged him to enlarge his aims, and in 1844 he visited Birr Castle for the purpose of inspecting the machine used in polishing the giant speculum of Parsonstown. In the construction of his new instrument, however, he eventually discarded the model there obtained, and worked on a method of his own, assisted by the supreme mechanical skill of James Nasmyth. The result was a Newtonian of exquisite definition, with an aperture of two, and a focal length of twenty feet, provided by a novel artifice with the equatoreal mounting, previously regarded as available only for refractors.

This beautiful instrument afforded to its maker, October 10, 1846, a cursory view of a Neptunian attendant. But the planet was then approaching the sun, and it was not until the following July that the observation could be verified, which it was completely, first by Lassell himself, and somewhat later by Otto Stuve and Bond of Cambridge (U.S.). When it is considered that this remote object shines by reflecting sunlight reduced by distance to 1/900th of the intensity with which it illuminates our moon, the fact of its visibility, even in the most perfect telescopes, is a somewhat surprising one. It can only, indeed, be accounted for by attributing to it dimensions very considerable for a body of the secondary order. It shares with the moons of Uranus the peculiarity of retrograde motion; that is to say, its revolutions, running counter to the grand current of movement in the solar system, are performed from east to west, in a plane inclined at an angle of 35 deg. to that of the ecliptic. Their swiftness serves to measure the mass of the globe round which they are performed. For while our moon takes twenty-seven days and nearly eight hours to complete its circuit of the earth, the satellite of Neptune, at a distance not greatly inferior, sweeps round its primary in five days and twenty-one hours, showing (according to a very simple principle of computation) that it is urged by a force seventeen times greater than the terrestrial pull upon the lunar orb. Combining this result with those of Professor Barnard’s and Dr. See’s recent measurements of the small telescopic disc of this farthest known planet, it is found that while in _mass_ Neptune equals seventeen, in _bulk_ it is equivalent to forty-nine earths. This is as much as to say that it is composed of relatively very light materials, or more probably of materials distended by internal heat, as yet unwasted by radiation into space, to about five times the volume they would occupy in the interior of our globe. The fact, at any rate, is fairly well ascertained, that the average density of Neptune is about twice that of water.

Historic Beer Birthday: Max Henius

June 16, 2018 By Jay Brooks 4 Comments

Today is the birthday of Max Henius (June 16, 1859–November 15, 1935). He “was a Danish-American biochemist who specialized in the fermentation processes. Max Henius co-founded the American Academy of Brewing in Chicago.”

Max Henius, at left, at Rebild, Denmark.

Here’s his biography, from Wikipedia:

Max Henius was born in Aalborg, Denmark. His parents were Isidor Henius (1820–1901) and Emilie (née Wasserzug) Henius (1839–1913), both Polish Jewish immigrants. His father, who was born in Thorn, West Prussia, now Torun, Poland, emigrated to Denmark in 1837 and continued his work for spirits distillers to improve and standardise production and later – 15 January 1846 – co-founded one distillery, Aalborg priviligerede Sirup- og Sprtitfabrik, that was later, together with several other distilleries, consolidated into De Danske Spritfabrikker in 1881, a Danish distillery which is now – since 2012 – part of the Norwegian Arcus Group, which closed the distillery in Aalborg in 2015, moving production to Norway instead. Isidor Henius also owned a small castle in Aalborg, now called Sohngaardsholm Slot. Since 2005, it has been the site of a gourmet restaurant.

Max Henius was educated at the Aalborg Latin School and went on to study at the Polytechnic Institute in Hanover, Germany He attended the University of Marburg, earning his Ph.D. degree in chemistry during 1881. His father sold the distillery that same year. Max Henius subsequently emigrated from Aalborg to the United States in 1881 at the age of 22, settling in Chicago. His younger brother, Erik S. Henius, (1863- 1926) remained in Denmark where he was Chairman of the Danish Export Association.

Initially he was employed by the Northern Pacific Railway on an assignment to test the waters between Fargo, North Dakota, and Bozeman, Montana. In 1886, he opened a drug store. Subsequently he formed Wahl & Henius, an institute for chemical and mechanical analysis, with his former schoolmate, Robert Wahl (1858-1937). Founded in 1891, the Chicago-based American Brewing Academy (later known as the Wahl-Henius Institute of Fermentology) was one of the premier brewing schools of the pre-prohibition era. This institute was later expanded with a brew master school that operated until 1921.

At the beginning of the twentieth century, Max Henius became interested in Danish-American organizations in Chicago. Funds were being raised by Danish Americans to purchase 200 acres (0.81 km2) of heather-covered hills, located in part of Rold Forest (Danish: Rold Skov), Denmark’s largest forest. In 1912 Max Henius presented the deed to H.M. King Christian X as a permanent memorial from Danish Americans. Rebild National Park (Danish: Rebild Bakker) is today a Danish national park situated near the town of Skørping in Rebild municipality, Region Nordjylland in northern Jutland, Denmark. Every July 4 since 1912, except during the two world wars, large crowds have gathered in the heather-covered hills of Rebild to celebrate American Independence Day. On the slope north of Rebild, where the residence of Max Henius was once located, a bust was placed in his memory.

And here’s Randy Mosher’s entry from the Oxford Companion to Beer of the Wahl-Henius Institute of Fermentology:

Wahl-Henius Institute of Fermentology
is a brewing research laboratory and school in Chicago that operated between 1886 and 1921.

Founded in 1886 by Dr Robert Wahl and Dr Max Henius as the Wahl & Henius, the name was changed to the Scientific Station for Brewing of Chicago and then to the Institute of Fermentology before becoming the Wahl-Henius Institute. Its educational division, the American Brewing Academy, was created in 1891.

The school and laboratory operated successfully until Prohibition, when the near dissolution of the brewing trade forced its closure and sale to the American Institute of Baking, which retains the nucleus of the Wahl-Henius library.

Wahl-Henius would perhaps be mostly forgotten today if it were not for its role as publisher of two important beer texts. The Wahl-Henius Handy Book of Brewing, Malting and the Auxillary Trades, coauthored by Wahl and Henius, is a comprehensive and wide-ranging view into American brewing in 1901. It also contains basic chemical analyses of many contemporary American and European beers, providing an unusually valuable window into the brewing past. J. P. Arnold’s 1911 Origin and History of Beer and Brewing is an exhaustive romp through thousands of years of beer history.

And this bust of Henius is in the Rebild National Park in Denmark. Henius organized fund-raising and “in 1911, almost 200 acres of the hilly countryside were bought with funds raised by Danish Americans. In 1912, Max Henius presented the deed to the land to his Majesty King Christian X as a permanent memorial to Danish Americans. Later the Danish government added to the land, that now features a beautiful natural park.”

And this is from the Chicago Midwest Rebild Chapter:

As we celebrate the 100th anniversary of the Rebild Society, I find it fascinating to look at the lives of its builders in the context of their times. It is hard to imagine a more dynamic time of porous borders and explosive growth than the late 19th century. Probably the name most closely associated with the founding of the Rebild Society is Max Henius. I had the good fortune to come across a biography of Henius written by his associates shortly after his death, and much of what I have written of Henius is largely based on that biography.

The first Europeans to come to Chicago were Pere Marquette and Louis Joliet in 1673 when they claimed Midwestern North America for Nouvelle France. Marquette and Joliet traveled up the Illinois River and portaged to the Chicago River and down to Lake Michigan. Joliet called for a canal to be built to connect the Illinois and Chicago rivers to stimulate trade and help France establish an economic empire in the New World. It was a prescient recommendation. Such a canal would indeed be built almost 200 years later, and an economic empire was ignited. Chicago would become the transport hub for a new nation, and not for New France.

In 1838, ten years before the canal was built connecting the Great Lakes and Mississippi watersheds, Max Henius’ father immigrated to Denmark from an impoverished Jewish family in Torun, Poland, traveling on foot to Aarhus, where his brother Jacob lived. The journey took six weeks. The elder Henius rose quickly in the distillery business first in Aarhus and then in København. He launched his own his distillery, Spritfabrikken in Aalborg in 1846, with money loaned from partners. In 1854 he returned to Torun to find a bride.

Born in 1859, Max was educated at the Aalborg Latin School and went on to study at the Polytechnic Institute in Hanover before matriculating at the University of Marburg, Germany. 1881 was a pivotal year for Max Henius. His father sold the distillery that Max had hoped to take over, and he had fallen in love with Johanne Heiberg. Both families disapproved of the relationship and Max Henius decided to immigrate to the US and subsequently send for his fiancée to come and marry him. Interestingly, a contemporary who would also become a very famous Danish-American, Jens Jensen, would immigrate to the US three years later partly because his prospective partner also did not meet family approval. A fellow student from Hannover and Warburg, Robert Wahl, told Max of the multiple opportunities available in the US, and later would partner with Henius in a very successful business.

Already in 1870 immigrants made up a larger proportion of the city’s population (48 percent) than any other place in North America. Chicago was quickly rebuilding after its massive destruction by fire in 1871 and Danish immigration was beginning to swell. Max Henius arrived in Chicago in October of 1881. Although he was a well educated and degreed chemist, his first jobs were as a door to door book salesman, errand boy for a pharmacy, and as a coal trimmer. Two years later he was employed by the Northern Pacific Railway to test the waters between Fargo, North Dakota and Bozeman, Montana but returned to Chicago to marry Johanne on June 4, 1883. With his savings he opened a drug store and subsequently formed Wahl & Henius, Analytical and Consulting Chemists with a lab at the back of the store. They established themselves as authorities on yeast culture and brewing.

Chicago was at this time one of the most rapidly growing cities in the world, the Shanghai of the late 19th century. Population growth was meteoric, fueled by decade after decade of immigration. But it was a wide open and divided city and hardly immune to the controversies of its time. May 1, 1886 saw a massive demonstration by workers (well advertised in the immigrant press) in favor of the eight-hour working day. Three days later the conflict culminated in a violent confrontation. The 1886 Haymarket Massacre took place in Chicago when an unknown person threw a dynamite bomb at police as they dispersed a public meeting. Chicago police fired on workers during a general strike for the eight-hour workday, killing several demonstrators and resulting in the deaths of several police officers. International Workers’ Day is the commemoration of the Haymarket Massacre. Ironically this would become a holiday officially celebrated throughout the Soviet bloc in the next century.

Henius did become involved in some of the public issues of this time. In 1892 a typhoid epidemic broke out in Chicago. Sewage was discharged into the Chicago River and subsequently found it way into Lake Michigan where Chicago’s water supply was tapped. Henius examined milk samples that were watered down and publicly spoke out on his findings. The waters of Lake Michigan were mapped bacteriologically so the water cribs were moved farther out in Lake Michigan.

Henius was very active in various Danish immigrant organizations, including the Danish-American Association, formed in Chicago in 1906. The idea for a Danish-American festival to be held in Denmark actually came from Ivar Kirkegaard, a Danish-American poet and editor. The first Danish-American rally was held in 1908 at Krabbesholm Folk High School on Skive Fjord. En route to the Krabbesholm festival, Henius was visiting Aarhus, when he learned of the planning for a national exposition to be held in Aarhus the following summer. He proposed to his fellow association members that they organize a Danish-American meeting for July 4, 1909. They filled an auditorium and persuaded the crown prince, later King Christian X, Georg Brandes and other noted Danes to speak at the event. Three years later Rebild Park was purchased by Danish Americans and set aside as a park, with the understanding that the site would be used to celebrate the 4th of July. Rebild Park was dedicated in 1912, and the first festival in Rebild was held on August 5, 1912.

Later Henius would found and head the Jacob A. Riis League of Patriotic Service to act as a clearing house for patriotic activities for Danish Americans during the First World War. The League grew out of a committee that managed the 3rd Liberty Load drive in Chicago among Danish-Americans. It also had among its objectives the preservation of Danish culture in America. Its influence was used with President Woodrow Wilson to include the question of the Danish border with Germany in the post war peace settlement. Henius would also be instrumental in establishing and supporting the Danes Worldwide Archives in Aalborg, initially housed in his childhood home of Sohngårdsholm.

Immigration has always been a controversial subject and resisted with varying degrees of success throughout history. But looking backwards one can only conclude it has been to our good fortune, and that our societies have been quite enriched and rejuvenated by the dynamism that immigrants have brought to us.

And Gary Gillman also has a nice overview of Henius’ life in a blog post last year, entitled Max Henius, Star of American Brewing Science.

Historic Beer Birthday: Max Delbrück

June 16, 2018 By Jay Brooks Leave a Comment

Today is the birthday of Max Emil Julius Delbrück (June 16, 1850-May 4, 1919). He was a German chemist who spent most of his career exploring the fermentation sciences.

His Wikipedia entry is short:

Delbrück was born in Bergen auf Rügen. He studied chemistry in Berlin and in Greifswald. In 1872 he was made assistant at the Academy of Trades in Berlin; in 1887 he was appointed instructor at the Agricultural College, and in 1899 was given a full professorship. The researches, carried out in part by Delbrück himself, in part under his guidance, resulted in technical contributions of the highest value to the fermentation industries. He was one of the editors of the Zeitschrift für Spiritusindustrie (1867), and of the Wochenschrift für Brauerei. He died in Berlin, aged 68.

And here’s his entry from Today in Science:

Max Emil Julius Delbrück was a German chemist who spent a forty-five year career leading development in the fermentation industry. He established a school for distillation workers, a glass factory for the manufacture of reliable apparatus and instruments, and an experimental distillery. Giving attention to the raw resources, he founded teaching and experimental institutions to improve cultivation of potatoes and hops. He researched physiology of yeast and application in the process of fermentation, production of pure cultures, and the action of enzymes. He started the journals Zeitschrift fur Spiritus-Industrie (1867) and Wochenschrift für Brauerei, for the alcohol and brewery industries, which he co-edited.

Over the years, I’ve found a few great Delbrück quotes:

“Yeast is a machine.”

— Max Delbrück, from an 1884 lecture

“With the sword of science and the armor of Practice, German beer will encircle the world.”

          — Max Delbrück, from an address about yeast and fermentation in the
               brewery, to the German Brewing Congress as Director of the Experimental
               and Teaching Institute for Brewing in Berlin, June 1884

Historical Beer Birthday: John Lofting

June 15, 2018 By Jay Brooks Leave a Comment

Today is as good a day as any to celebrate the birthday of John Lofting (1659–June 15, 1742). Like many people born centuries ago who weren’t royal or otherwise well-born, we don’t know the exact day he was born, but we do know that he died today. Lofting was a Dutchman who lived in London as an adult, and patented several devices, the most famous of which was the fire engine, but he may also have been responsible for the beer engine.

Here’s his Wikipedia entry:

Originally Jan Loftingh, John Lofting was an engineer and entrepreneur from the Netherlands. His parents were Herman and Johanna. He moved to London, England, before 1686. He patented two inventions being the “sucking worm engine” (a fire engine) and a horse-powered thimble knurling machine. His mill was set up in Islington, where Lofting Road is named after him. However, in or about 1700, he moved his main operation to Great Marlow in Buckinghamshire to take advantage of the River Thames’ ability to turn a water wheel which improved productivity, enabling the production of over 2 million thimbles per year.

The Sucking Worm Engine, from the British Museum.

And while Joseph Bramah patented the first practical beer engine, Lofting’s design made it possible for Bramah to build on and create his. Although there’s little I could find specific about Lofting’s invention, it is mentioned in the Wikipedia entry for the beer engine:

A beer engine is a device for pumping beer from a cask in a pub’s cellar.

The beer engine was invented by John Lofting, a Dutch inventor, merchant and manufacturer who moved from Amsterdam to London in about 1688 and patented a number of inventions including a fire hose and engine for extinguishing fires and a thimble knurling machine as well as a device for pumping beer. The London Gazette of 17 March 1691 stated “the patentee hath also projected a very useful engine for starting of beers and other liquors which will deliver from 20 to 30 barrels an hour which are completely fixed with brass joints and screws at reasonable rates.”

The locksmith and hydraulic engineer Joseph Bramah developed beer pumping further in 1797.

The beer engine is normally manually operated, although electrically powered and gas powered pumps are occasionally used; when manually powered, the term handpump is often used to refer to both the pump and the associated handle.

The beer engine is normally located below the bar with the visible handle being used to draw the beer through a flexible tube to the spout, below which the glass is placed. Modern hand pumps may clamp onto the edge of the bar or be mounted on the top of the bar.

A pump clip is usually attached to the handle by a spring clip giving the name and sometimes the brewery, beer type and alcoholic strength of the beer being served through that handpump.

The handle of a handpump is often used as a symbol of cask ale. Keg beer dispensers usually feature illuminated countertop fittings behind which a handle opens a valve that allows the gas pressure in the keg to force beer to the attached spout.

Historic Beer Birthday: William S. Gossett

June 13, 2018 By Jay Brooks Leave a Comment

Today is the birthday of William Sealy Gosset (June 13, 1876–October 16, 1937). He “was an English statistician. He published under the pen name Student, and developed the Student’s t-distribution.” He also worked his entire career for Guinness Brewing, and was trained as a chemist, but it was his pioneering work in statstics, in which he was self-taught, that he is remembered today.

Here’s his biography, from Wikipedia:

Born in Canterbury, England to Agnes Sealy Vidal and Colonel Frederic Gosset, Gosset attended Winchester College before studying chemistry and mathematics at New College, Oxford. Upon graduating in 1899, he joined the brewery of Arthur Guinness & Son in Dublin, Ireland.

As an employee of Guinness, a progressive agro-chemical business, Gosset applied his statistical knowledge – both in the brewery and on the farm – to the selection of the best yielding varieties of barley. Gosset acquired that knowledge by study, by trial and error, and by spending two terms in 1906–1907 in the biometrical laboratory of Karl Pearson. Gosset and Pearson had a good relationship. Pearson helped Gosset with the mathematics of his papers, including the 1908 papers, but had little appreciation of their importance. The papers addressed the brewer’s concern with small samples; biometricians like Pearson, on the other hand, typically had hundreds of observations and saw no urgency in developing small-sample methods.

Another researcher at Guinness had previously published a paper containing trade secrets of the Guinness brewery. To prevent further disclosure of confidential information, Guinness prohibited its employees from publishing any papers regardless of the contained information. However, after pleading with the brewery and explaining that his mathematical and philosophical conclusions were of no possible practical use to competing brewers, he was allowed to publish them, but under a pseudonym (“Student”), to avoid difficulties with the rest of the staff. Thus his most noteworthy achievement is now called Student’s, rather than Gosset’s, t-distribution.

Gosset had almost all his papers including The probable error of a mean published in Pearson’s journal Biometrika under the pseudonym Student. It was, however, not Pearson but Ronald A. Fisher who appreciated the importance of Gosset’s small-sample work, after Gosset had written to him to say I am sending you a copy of Student’s Tables as you are the only man that’s ever likely to use them!. Fisher believed that Gosset had effected a “logical revolution”. Fisher introduced a new form of Student’s statistic, denoted t, in terms of which Gosset’s statistic was {\displaystyle z={\frac {t}{\sqrt {n-1}}}} z=\frac{t}{\sqrt{n-1}}. The t-form was adopted because it fit in with Fisher’s theory of degrees of freedom. Fisher was also responsible for applications of the t-distribution to regression analysis.

Although introduced by others, Studentized residuals are named in Student’s honour because, like the problem that led to Student’s t-distribution, the idea of adjusting for estimated standard deviations is central to that concept.

Gosset’s interest in the cultivation of barley led him to speculate that the design of experiments should aim not only at improving the average yield but also at breeding varieties whose yield was insensitive to variation in soil and climate, i.e. robust. This principle only appeared in the later thought of Ronald Fisher, and then in the work of Genichi Taguchi during the 1950s.

In 1935, Gosset left Dublin to take up the position of Head Brewer, in charge of the scientific side of production, at a new Guinness brewery at Park Royal in northwestern London. He died two years later in Beaconsfield, England, of a heart attack.

Gosset was a friend of both Pearson and Fisher, a noteworthy achievement, for each had a massive ego and a loathing for the other. He was a modest man who once cut short an admirer with the comment that “Fisher would have discovered it all anyway.”

And this biography is from the MacTutor History of Mathematics archive:

William Sealey Gosset was born on June 13, 1876 in Canterbury, England where he was the oldest of five children. He died at the age of 61 in Beaconsfield, England on October 16, 1937. He attended the Royal Military Academy in Woolwich to b ecome an engineer before he was rejected because of poor eyesight. William Gosset was never employed as a statistician. In a world of quarrelsome statistics, but he got along with everyone. He was a very helpful, quiet, patient and loyal person.

He went to school at Winchester and was well educated before entering the New College in Oxford. Here he won a first degree in chemistry in 1899. After getting his degree as a chemist, he got a job at Guinness brewery in Dublin in 1899, where he did important work on statistics, but her was never hired at a statistician. It was his environment at Guinness’ that made him a statistician. The brewery was interested in how they could make the best beer.

In 1900, the Guinness Research Laboratory was opened, which was head by the most distinguished brewing chemist, Horace Brown. Horace Brown along with the other brews were wondering how to get the raw materials for brewing beer at the cheapest but getting the best. There were many factors that they had to take into account such as varieties of barley and hops, what conditions of dying, cultivation and maturing factors.

After a few years of research, given that they were given a free hand to explore the conditions of brewing. This gave Gosset a chance to work as a statistician. He was able to take the data from the different examples of brewing to help find out which way was the best. As the young brewers work together, it seemed natural for them to take the data to Gosset to solve the numerical problems.

Gosset, in 1903, could calculate standard errors. In 1904 he wrote on the brewing of beer. This report lead to Karl Pearson consulting Gosset. Gosset met Pearson in July of 1905 when they had long talk together. Pearson, in an hour and a half, m ade Gosset understand the theory of standard errors. Gosset went back to the brewery and practiced those method for the next year. The meeting was also successful in which Pearson got Gosset to take up the study of the law of error.

Gosset wrote paper in his spare time under the name “Student.” His paper were on the probability of error of the mean and of the correlation coefficient for publication. Gosset even managed to run cooperative experiments with Hunter a nd Bennett at Ballinacurra, Buffin at Cambridge, and Beaven at Warminster in the testing of seeds against other seeds. Gosset also work with R.A. Fisher. The funny part is that Fisher did not get along Pearson, but Gosset studied under Pearson and also got along with Fisher.

To quickly recap William Gosset, he was born in 1876 and died in 1937. He did mathematical research for beer brewing, but had the problem working with only a small sample size. He work on the concept of probable errror of a mean. He also analysi sed an extended and broad range of problems such as the counting with a haemacytometer, probable error of a correlation coefficient, cereals, agronomy and the Lanarkshire milk experiment.

A very personal friend, McMullen, said this about Gosset, “he was a very kindly and tolerant and absolutely devoid malice. He rarely spoke about personal matters but when his opinion was well worth listening to and not in the least superficia l.”

Pricenomics has a good overview of Gossett’s contributions to mathematics and statistics, entitled The Guinness Brewer Who Revolutionized Statistics.

Historic Beer Birthday: Carl von Linde

June 11, 2018 By Jay Brooks Leave a Comment

Today is the birthday of Carl Paul Gottfried Linde (June 11, 1842–November 16, 1934). He “was a German scientist, engineer, and businessman. He discovered a refrigeration cycle and invented the first industrial-scale air separation and gas liquefaction processes. These breakthroughs laid the backbone for the 1913 Nobel Prize in Physics. Linde was a member of scientific and engineering associations, including being on the board of trustees of the Physikalisch-Technische Reichsanstalt and the Bavarian Academy of Sciences and Humanities. Linde was also the founder of what is now known as The Linde Group, the world’s largest industrial gases company, and ushered the creation of the supply chain of industrial gases as a profitable line of businesses. He was knighted in 1897 as Ritter von Linde.”

His importance to brewing, especially yo lager beers, is undeniable. His first refrigerating machines were built for breweries. This is situation prior to his inventions, from the University of Chicago:

Before the development of mechanical refrigeration technologies, brewers were reliant on ice harvested from lakes and ponds and stored in ice-houses. The invention of mechanical refrigeration machines provided commercial brewers with the technology necessary to keep beer for longer periods of time. Refrigeration technology was also used in special railroad boxcars, permitting brewers to ship their product over longer distances. One of the most successful early designs for a mechanical refrigeration system was invented by Carl von Linde (a professor at Munich Polytechnic School) and was an ammonia-based vapor-compression system.

One of the drawing from his first patent, in 1873.

This history of the development of Linde’s refrigeration machines is from a brochure prepared by his the company he founded, The Linde Group.

Initial contacts with breweries

After von Linde had published his ideas in 1870 and 1871 in the Polytechnic Association’s “Bavarian Industry and Trade Journal,” which he also edited, a development was set in motion that would determine the direction of the entire rest of his life. His articles on refrigeration technology had aroused the interest of brewers who had been looking for a reliable year-round method of refrigeration for the fermentation and storage of their beer. In the summer of 1871 an agreement was made between von Linde, Austrian brewer August Deiglmayr (Dreher Brewery) and Munich brewer Gabriel Sedlmayr to build a test machine according to Linde’s design at the Spaten Brewery. With their help, Linde’s ideas would be put into practice, so that a refrigeration unit could then be installed at the Dreher Brewery, the largest brewery in Austria, in the hot, humid city of Trieste (now part of Italy).

The construction plans were finally completed in January 1873 and the patent applied for. The Bavarian patent required, however, that the machine be in operation within one year. Therefore von Linde and Sedlmayr placed an order with Maschinenfabrik Augsburg that same month to build it. And with some effort they succeeded in starting operation by the important patent deadline in January 1874. Of course, the first machine did have its difficulties.

The main problem was that von Linde’s mercury seal did not work properly so that the methyl ether used as the refrigerant leaked out of the compressor. In Linde’s words, “This design was not a suitable solution for the requirements of practical use. So it seemed imperative to build a second machine.”

In order to finance it, von Linde assigned part of the patent rights to Sedlmayr, to locomotive builder Georg Krauss and to the director of Maschinenfabrik Augsburg, Heinrich von Buz. In return, they provided the funds needed for the development, building and testing of a new refrigeration machine.

Building the second refrigeration machine

With his student and assistant Friedrich Schipper, von Linde designed a new compressor, which had a significantly simpler and more effective seal. The sealing material used in the newly designed gland construction was glycerin and the more efficient ammonia was used as the refrigerant. The new machine weighed and cost only half as much as its predecessor.

In the spring of 1875 Linde ordered the new compressor from Maschinenfabrik Augsburg and submitted it for a Bavarian patent, which was awarded on March 25, 1876 for ten years. He received the German Reichspatent in August 1877.

“The very first trials with this second compressor yielded fully satisfactory results,” said von Linde, not without pride. The machine was sold to the Dreher Brewery in September 1876, erected under Schipper’s supervision and started up in spring 1877. It ran until 1908, providing refrigeration and dehumidification

Technical breakthrough

But despite this success, Linde created a third design immediately after the second machine was installed at Dreher, turning his attention to gas pumps, which were already widely used. This third, horizontal design proved to be the best cold vapor machine on the market in terms of its price/performance ratio and became the standard type of Linde compressor for decades to come. During the more than six-year development and experimentation phase, a reliable solution also had to be found for distributing the generated cold. After long trials, in executing an order for the Heineken Brewery in Rotterdam, von Linde developed a method of circulating cold saltwater brine in a pipe cooling system (natural convection cooling), which was installed on the ceiling of the refrigeration rooms.

And this inset is about the company’s “First customers and partners: brewers.”

In 1840, many continental European breweries switched to bottom fermented lager production (in contrast to the “English” top-fermented brown beers or ales) because the beer remained fresh longer and customers preferred the taste. The ice machine described by von Linde seemed ideal for achieving the required lower temperatures and to ensure precise cooling control. So it is no wonder that some major brewers showed great interest in this invention.

Gabriel Sedlmayr of the Munich Spaten Brewerey was willing to let von Linde experiment with an early refrigeration machine in his brewery in the early 1870s. The first unit functioned passably well, but was too large and had numerous flaws. The drawings submitted for the patent showed that Sedlmayr himself had a hand in the second version, which was significantly smaller in size and worked well. This unit was sold to the Trieste Dreher Brewery for air cooling.

With Sedlmayr as an intermediary, the Rotterdam Heineken Brewery under its director Feldmann ordered an ice machine in 1877 for ice production. In his collaboration with the Heineken Brewery, Linde developed “natural convection cooling” with a system of cooling pipes under the ceiling of the cellar. Feldmann in turn put von Linde in contact with J. C. Jacobsen, head of the Carlsberg Brewery in Copenhagen, who ordered a large refrigeration unit in 1878.

Karl Lang, technical adviser and supervisory board member of several Rhineland breweries, also played a significant role during the founding period of the “Gesellschaft für Linde’s Eismaschinen.” He introduced Linde to brewery director Gustav Jung, who not only ordered a refrigeration unit but also became, with Lang and banker Moritz von Hirsch, a shareholder and Supervisory Board member of the Linde Company.

The connection between the Linde Company and brewery directors was maintained to some extent over several generations. After the death of Karl Lang in 1894 his position as chairman of the Supervisory Board was taken over by Gustav Jung, followed by his son Adolf Jung in 1886. Carl Sedlmayr took over for his father Gabriel on the Supervisory Board and in 1915, the third generation of this family followed with Anton Sedlmayr. The Jung and Sedlmayr families held their Supervisory Board seats until after the Second World War.

Here’s Linde’s entry from the Oxford Companion to Beer, written by Horst Dornbush.

Linde, Carl von
was a 19th-century German engineer and one of the world’s major inventors of refrigeration technology. See refrigeration. Starting in the middle of the 18th century, many people before Linde had tinkered with artificial refrigeration contraptions, but Linde was the first to develop a practical refrigeration system that was specifically designed for keeping fermenting and maturing beer cool—in Linde’s case, Bavarian lagers—during the hot summer months. Linde was born in the village of Berndorf, in Franconia, in 1842, at a time when warm-weather brewing was strictly forbidden in his native Bavaria; no one was allowed to brew beer between Saint George’s Day (April 23) and Michael’s Day (September 29). This was to avoid warm fermentations, which provided ideal habitats for noxious airborne bacteria to proliferate and caused yeasts to produce undesirable fermentation flavors. Both made summer beers often unpalatable. Summer brewing prohibition had been in force since 1553 and was only lifted in 1850, by which time Bavarian brewers had learned to pack their fermentation cellars with ice they had laboriously harvested in the winter from frozen ponds and lakes. There had to be a better way to keep beer cold…and that was just the challenge for a budding mechanical engineering professor like Linde, who had joined Munich’s Technical University in 1868. See weihenstephan. The basic principle of refrigeration had been understood for centuries. Because cold is merely the absence of heat, to make things cold, one must withdraw heat. Compressing a medium generates heat; subsequently decompressing or evaporating it quickly absorbs heat from its environment. Devices based on this principle are now generally known as vapor-compression refrigeration systems; apply this to a fermenting or lagering vessel, and it becomes a beer-cooling system. For Linde, the next question was the choice of refrigerant. Initially he experimented with dimethyl ether but eventually settled on ammonia because of its rapid expansion (and thus cooling) properties. He called his invention an “ammonia cold machine.” Linde had received much of the funding for this development from the Spaten Brewery in Munich, which was also the first customer to install the new device—then still driven by dimethyl ether—in 1873. By 1879, Linde had quit his professorship and formed his own “Ice Machine Company,” which is still in operation today as Linde AG, headquartered in Wiesbaden, Germany. By 1890, Linde had sold 747 refrigeration units machines to various breweries and cold storage facilities. He continued to innovate and invented new devices most of his life, including equipment for liquefying air, and for the production of pure oxygen, nitrogen, and hydrogen. In 1897 he was knighted, and from then on could append the honorific “von” to his surname. He died a prosperous industrialist in Munich in 1934, at the age of 92, and today Linde AG is a leading gases and engineering company with almost 48,000 employees working in more than 100 countries worldwide. For all his many accomplishments, Linde’s pioneering work in artificial beer cooling technology is perhaps his most enduring legacy.

Historic Beer Birthday: John Gilroy

May 30, 2018 By Jay Brooks Leave a Comment

Today is the birthday of John Gilroy (May 30, 1898-April 11, 1985). While not a brewer or even brewery owner, he was nonetheless at least partially responsible for the success of Guinness with his iconic advertising that he created for them beginning in 1928.

Here’s his entry from Wikipedia.

“Born in Whitley Bay, Northumberland, England, Gilroy attended Durham University until his studies were interrupted by World War I, during which he served with the Royal Field Artillery. He resumed studying at the Royal College of Art in London, where he remained as a teacher. He taught at Camberwell College of Arts.

In 1925, he gained employment at S.H. Benson’s advertising agency, where he created the iconic advertisement art for Guinness featuring the Zoo Keeper and animals enjoying Guinness. He worked with Dorothy L. Sayers. He was also an accomplished portrait painter, numbering Royalty, Politicians, Actors and many others amongst his sitters. He worked in his large studio at 10 Holland Park, London, the former home and studio of Sir Bernard Partridge. He was a long-standing and much loved member of the Garrick Club, where he was created a Life Member and Chairman of the Works of Art Committee 1970-1975. He was awarded and Honorary MA by Newcastle University in 1975, and was made a Freeman of the City of London in 1981.”

The Guinness Collectors Club has a more thorough biography:

John Gilroy (1898-1985) was a superb natural draughtsman and a versatile illustrator and artist who produced advertsising material, portraits, landscapes, murals and greeting cards.

Born on the 30th of May 1898 at Whitley Bay, Newcastle upon Tyne, he was one of a family of eight (five boys and three girls), born to John William Gilroy and his wife Elizabeth. William Gilroy was a marine landscape painter and technical draughtsman and it was obvious from an early age that John junior was going to follow in his footsteps. The young John practised copying cartoons from Punch and took on all kinds of work to pay for drawing materials. From the age of fifteen he was a cartoonist for the Evening Chronicle, Newcastle, commissioned to produce cartoons of well-known entertainers who played the Newcastle theatres.

John attended Sandyford School followed, in 1909, by Heaton Park Road Upper School. At this date his family was living at 25 Kingsley Place. In June 1912, he left Heaton Park and, having attained his drawing certificate, won a scholarship to Armstrong College Art School, Durham University to study under Professor K.G. Hatten.

The First World War interrupted Gilroy’s studies and he served with the Royal Field Artillery in France, Italy and Palestine. In September 1919 he resumed his studies taking a place at the Royal College of Art, London (RCA). During his time there he produced illustrations for the college student magazine and occasionally played in goal for the college football team. In 1920 he attained his Board of Education certificate and the RCA diploma in decorative painting. His work was also rewarded through scholarships and prizes, winning, in 1919, the North Lordbourne prize for composition and, in 1921, the college drawing prize and the British Institute Scholarship for decorative painting. In 1922 Gilroy won an RCA travelling scholarship in mural painting having missed the Prix de Rome by only one vote.

Gilroy graduated from the RCA in July 1923 but stayed on there until 1925 as a teacher. From 1924 to 1926 he also taught drawing from the figure in the evenings at the Camberwell School of Art. In 1924 he married Gwendoline Peri-Short who had been a fellow pupil at the RCA and three years later they had a son, John.

In 1925 Gilroy embarked on his long association with the advertising agency S H Benson Ltd (Benson’s). Although Benson’s was the first advertising agency for whom Gilroy worked as an in-house artist, he had already proven himself in the commercial art sphere. His earliest known piece of commercial art, dating from 1920 when he was still a student, was for a promotional leaflet for the Mangnall-Irving Thrust-Borer commissioned by the Hydraulic Engineering Co.

Gilroy’s early work at Benson’s is reputed to have been on campaigns for Skipper Sardines and Virol. During his time there he also worked on campaigns for Bovril, Macleans and Monk & Glass Custard. His first significant assignment was the Mustard Club campaign for Coleman’s of Norwich, on which he worked with fellow artist William Brearley and copywriters Oswald Greene and Dorothy L Sayers. Between 1926 and 1933 the pens of Gilroy and Brearley brought eccentric characters like Baron de Beef, Signor Spaghetti and Miss Di Gester to life on bill boards and in magazines everywhere.

In 1928 Benson’s won the Guinness advertising account and Gilroy became involved with the product with which his work is most closely associated. Gilroy’s first known Guinness poster was produced in 1930. Working with copywriters like Ronald Barton and Robert Bevan, Gilroy produced more than 100 press advertisements and nearly 50 poster designs for Guinness over 35 years. He is perhaps best remembered for his posters featuring the girder carrier and the wood cutter from the Guinness for Strength campaigns of the early 1930s and for the Guinness animals. The animals, including a lion, toucan, gnu and kangaroo, appeared, with their long-suffering zookeeper, on posters, press advertisements, show cards and waiter trays from the 1930s to the 1960s.

Gilroy continued to produce Guinness advertisements well into the 1960s even though he left Benson’s employment as an in-house artist in the 1940s to continue freelance work.

During the 1920s and succeeding decades commercial art was not Gilroy’s sole occupation; he began to build his reputation as a painterboth of portraits and landscapes. One of his earliest portrait commissions was to paint the future Edward V111 for the Royal Mid-Surrey Golf Club, of which Gilroy was a member and the Prince was patron.

In 1930, while the family was living at The Cottage, Hyde Park Road, Kew Gardens, Gilroy has his first painting, Gwen. exhibited at the Royal Academy. Throughout the 1930s Gilroy’s work continued to be exhibited at the Royal Academy and to appear on advertising boardings, in newspapers and even in the Radio Times. In 1941, with the onset of the blitz, the artist moved to Rasehill, Chorleywood Road, Rickmansworth. His wife and son moved to Cheltenham where, in the same year, he held a one-man exhibition of his work, which then travelled to Sunderland Public Art Gallery.

Throughout the war years, Gilroy’s work continued to be exhibited at the Royal Academy while his commercial art talents were employed by the Ministry of Information in campaigns such as Make-do-and-mend, Keep it under your hat and We want your kitchen waste. He also improved morale by painting murals at various Royal Air Force bases and produced a series of drawings-in-one-line of contemporary political and military figures, called Headlines, which appered in The Star.

By 1945, when his painting Diamond Setting was exhibited at the Royal Academy, the artist’s address was given as 6 Avenue Studios, Sydney Close, SW3. A year laterhe prodced another mural, this time in the bar of the Mrritt Arms Hotel near Greta Bridge on the estate of his close friend Major Morritt. The work at the Morritt Arms began on the 1st February 1946 and was completed within10 days. When Gilroy and his assistant proudly displayed the walls of the bar decorated with Dickensian figures, closer inspection revealed them to be caricatures of local people and staff from the hotel.

In 1949 Esme Jeudwine, a former pupil and portrait subject, introduced Gilroy to the Royle family and another long and successful association began. Gilroy produced five greeting card designs for Royle Publications Ltd (Royles) in that year with another 464 published designs over the next 35 year. In 1966, Gilroy was acting Art Director for Royles.

In 1950 Gilroy married Elizabeth Margaret Bramley (nee Outram Thwaite). The couple lived at 17 Queen’s Gate, Kensington, but moved a year later to 10 Holland Park Road, W14, the former home and studio of Sir Bernard Partridge, whose cartoons Gilroy had copied from Punch as a child. The magnificent studio at Holland Park Road saw the creation of advertising work for T.F. Carrington Van PostingLtd. where Gilroy was Head of the Art Department, and was regularly visited by members of the Royal Family, politicians, actors and many others who came to have theit portraits painted.

In 1957 Gilroy held another one-man exhibition this time at Leighton House Gallery and two years later produced a series of landscapes of McGill University, Montreal, to illustrate a book McGill, The Story of a University, edited by Hugh MacLennan. In 1970 Gilroy held a retrospective exhibition at Upper Grosvenor Galleries and three years later an exhibition of his humorous designs for Royles was held at the London headquarters of Austin Reed Ltd.

In his later years ‘Jack’ Gilroy was a longstanding and much loved member of the Garrick Club where he was Chairman of the Works of Art Committee and where a number of his portraits now hang. In 1975 Gilroy was awarded an honorary MA by Newcastle University and in 1981, now living at 6 Ryecroft Street, Fulham, he was appointed a Freeman of the City of London.

John Gilroy died at Guildford on the 11th April 1985, aged 86, and is buried at Ampney St Peter in Gloucestershire near the home of his son and three grandchildren.

He created the zoo animals and other popular characters for Guinness from either 1928 or the early 1930s (accounts differ), but the first one he did appears to be the Guinness for Strength ad featuring a steel girder in 1934. According to some accounts, it was so popular that people even started ordering a ‘girder’ in the pub.

The following year, the Toucan debuted, and quickly became one of the most recognizable of the Guinness animals, used in marketing and advertising by Guinness for over 45 years. Here’s the story of its design from History House:

The idea of using a toucan was born in the advertising agency of S.H.Benson in London. Staff included the talented artist John Gilroy was newly employed as the poster artist, and among the copywriting team was Dorothy L Sayers, now famous as a writer, poet and playwright, and best known for her amateur detective stories featuring Lord Peter Wimsey. She had started at the agency in 1922 and worked there while writing books in her spare time.

This team produced some memorable posters for Guinness including several posters in the whimsical “Zoo” series. These included a zoo keeper with a Guinness, a sea lion balancing drink on his nose, an ostrich with the shape of a swallowed glass halfway down its neck, a tortoise with a glass of stout on its back, and a toucan with two Guinness bottles balanced on its beak accompanied by the words.

If he can say as you can
“Guinness is good for you”
How grand to be a Toucan
Just think what Toucan do.

Gilroy remained with the advertising agency until 1960 during which time he designed many other Guinness posters. As to how animals came to be used in an advertising campaign was recalled later by Gilroy. “The Guinness family did not want an advertising campaign that equated with beer. They thought it would be vulgar. They also wanted to stress the brew’s strength and goodness. Somehow it led to animals.”

The toucan returned on several occasions on all types of advertising media and on memorabilia. In 1982 Guinness changed advertising agencies and it was decided that the toucan was no longer an effective advertising motif and it was dropped.

The text from that ad was actually written by Dorothy L. Sayers, who worked for the same advertising agency as Gilroy before she became a famous mystery writer, well-known for such characters as Lord Peter Wimsey, and others.

Gilroy’s first Toucan ad, from 1935.

And here’s a sample of some more of his work for Guinness.

And finally, by no means complete, these are other Guinness ads I’ve collected in a Flickr gallery, many of which are by John Gilroy.

Historic Beer Birthday: Eduard Buchner

May 20, 2018 By Jay Brooks Leave a Comment

Today is the birthday of Eduard Buchner (May 20, 1860-August 13, 1917). Buchner was a German chemist and zymologist, and was awarded with Nobel Prize in Chemistry in 1907 for his work on fermentation.

This is a short biography from The Famous People:

Born into an educationally distinguished family, Buchner lost his father when he was barely eleven years old. His elder brother, Hans Buchner, helped him to get good education. However, financial crisis forced Eduard to give up his studies for a temporary phase and he spent this period working in preserving and canning factory. Later, he resumed his education under well-known scientists and very soon received his doctorate degree. He then began working on chemical fermentation. However, his experience at the canning factory did not really go waste. Many years later while working with his brother at the Hygiene Institute at Munich he remembered how juices were preserved by adding sugar to it and so to preserve the protein extract from the yeast cells, he added a concentrated doze of sucrose to it. What followed is history. Sugar in the presence of enzymes in the yeast broke into carbon dioxide and alcohol. Later he identified the enzyme as zymase. This chance discovery not only brought him Nobel Prize in Chemistry, but also brought about a revolution in the field of biochemistry.

Eduard Buchner is best remembered for his discovery of zymase, an enzyme mixture that promotes cell free fermentation. However, it was a chance discovery. He was then working in his brother’s laboratory in Munich trying to produce yeast cell free extracts, which the latter wanted to use in an application for immunology.

To preserve the protein in the yeast cells, Eduard Buchner added concentrated sucrose to it. Bubbles began to form soon enough. He realized that presence of enzymes in the yeast has broken down sugar into alcohol and carbon dioxide. Later, he identified this enzyme as zymase and showed that it can be extracted from yeast cells. This single discovery laid the foundation of modern biochemistry.

One of the most important aspects of his discovery proving that extracts from yeast cells could elicit fermentation is that it “contradicted a claim by Louis Pasteur that fermentation was an ‘expression of life’ and could occur only in living cells. Pasteur’s claim had put a decades-long brake on progress in fermentation research, according to an introductory speech at Buchner’s Nobel presentation. With Buchner’s results, “hitherto inaccessible territories have now been brought into the field of chemical research, and vast new prospects have been opened up to chemical science.”

In his studies, Buchner gathered liquid from crushed yeast cells. Then he demonstrated that components of the liquid, which he referred to as “zymases,” could independently produce alcohol in the presence of sugar. “Careful investigations have shown that the formation of carbon dioxide is accompanied by that of alcohol, and indeed in just the same proportions as in fermentation with live yeast,” Buchner noted in his Nobel speech.

This is a fuller biography from the Nobel Prize organization:

Eduard Buchner was born in Munich on May 20, 1860, the son of Dr. Ernst Buchner, Professor Extraordinary of Forensic Medicine and physician at the University, and Friederike née Martin.

He was originally destined for a commercial career but, after the early death of his father in 1872, his older brother Hans, ten years his senior, made it possible for him to take a more general education. He matriculated at the Grammar School in his birth-place and after a short period of study at the Munich Polytechnic in the chemical laboratory of E. Erlenmeyer senior, he started work in a preserve and canning factory, with which he later moved to Mombach on Mainz.

The problems of chemistry had greatly attracted him at the Polytechnic and in 1884 he turned afresh to new studies in pure science, mainly in chemistry with Adolf von Baeyer and in botany with Professor C. von Naegeli at the Botanic Institute, Munich.

It was at the latter, where he studied under the special supervision of his brother Hans (who later became well-known as a bacteriologist), that his first publication, Der Einfluss des Sauerstoffs auf Gärungen (The influence of oxygen on fermentations) saw the light in 1885. In the course of his research in organic chemistry he received special assistance and stimulation from T. Curtius and H. von Pechmann, who were assistants in the laboratory in those days.

The Lamont Scholarship awarded by the Philosophical Faculty for three years made it possible for him to continue his studies.

After one term in Erlangen in the laboratory of Otto Fischer, where meanwhile Curtius had been appointed director of the analytical department, he took his doctor’s degree in the University of Munich in 1888. The following year saw his appointment as Assistant Lecturer in the organic laboratory of A. von Baeyer, and in 1891 Lecturer at the University.

By means of a special monetary grant from von Baeyer, it was possible for Buchner to establish a small laboratory for the chemistry of fermentation and to give lectures and perform experiments on chemical fermentations. In 1893 the first experiments were made on the rupture of yeast cells; but because the Board of the Laboratory was of the opinion that “nothing will be achieved by this” – the grinding of the yeast cells had already been described during the past 40 years, which latter statement was confirmed by accurate study of the literature – the studies on the contents of yeast cells were set aside for three years.

In the autumn of 1893 Buchner took over the supervision of the analytical department in T. Curtius’ laboratory in the University of Kiel and established himself there, being granted the title of Professor in 1895.

In 1896 he was called as Professor Extraordinary for Analytical and Pharmaceutical Chemistry in the chemical laboratory of H. von Pechmann at the University of Tübingen.

During the autumn vacation in the same year his researches into the contents of the yeast cell were successfully recommenced in the Hygienic Institute in Munich, where his brother was on the Board of Directors. He was now able to work on a larger scale as the necessary facilities and funds were available.

On January 9, 1897, it was possible to send his first paper, Über alkoholische Gärung ohne Hefezellen (On alcoholic fermentation without yeast cells), to the editors of the Berichte der Deutschen Chemischen Gesellschaft.

In October, 1898, he was appointed to the Chair of General Chemistry in the Agricultural College in Berlin and he also held lectureships on agricultural chemistry and agricultural chemical experiments as well as on the fermentation questions of the sugar industry. In order to obtain adequate assistance for scientific research, and to be able to fully train his assistants himself, he became habilitated at the University of Berlin in 1900.

In 1909 he was transferred to the University of Breslau and from there, in 1911, to Würzburg. The results of Buchner’s discoveries on the alcoholic fermentation of sugar were set forth in the book Die Zymasegärung (Zymosis), 1903, in collaboration with his brother Professor Hans Buchner and Martin Hahn. He was awarded the Nobel Prize in 1907 for his biochemical investigations and his discovery of non-cellular fermentation.

Buchner married Lotte Stahl in 1900. When serving as a major in a field hospital at Folkschani in Roumania, he was wounded on August 3, 1917. Of these wounds received in action at the front, he died on the 13th of the same month.
