Today is the 53rd birthday of James Costa. James is a brewer and co-founder of Oakland Brewing, and is also currently brewing at Half Moon Bay Brewing. But James has certainly made the rounds, and has also brewed for Moylan’s, Santa Cruz Aleworks, E.J. Phair and others. James is justly famous for his big, hoppy beers like the wonderful Sticky Zipper. Join me in wishing James a very happy birthday.

Beer Birthday: Rick Kempen

June 14, 2025 By Jay Brooks Leave a Comment

Today is the birthday or Rick Kempen, who is a Bierambassadeur at Bier&cO in Amsterdam, which is a specialized beer import, export and wholesale company. Originally, Rick studied economics but applied that to beer, working as a bartender before turning his attention to the exporting and importing of beer. I first met Rick at the Brussels Beer Challenge in 2014, and run into him frequently on the international beer judging circuit, and he’s definitely a fun person to share a pint with. Join me in wishing Rick a very happy birthday.

Historic Beer Birthday: William S. Gossett

June 13, 2025 By Jay Brooks Leave a Comment

guinness-new
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 statistics, in which he was self-taught, that he is best remembered for today.

William_Sealy_Gosset

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: Constant Vanden Stock

June 13, 2025 By Jay Brooks Leave a Comment

Today is the birthday of Constant Vanden Stock (June 13, 1914-April 19, 2008). While he was best known for his exploits in football/soccer, he also ran his family’s business, Belle-Vue Brewery. That brewery was founded by his father, Philémon Vandenstock, in 1913. Constant’s father was captured by the Nazis in World War 2, and was sent to a concentration camp, but died one week after being released in 1945. After the war, Constant re-opened the brewery and continued to run it until the business was effectively acquired by Interbrew, now AB-InBev, in 1988.

Constant on his 90th birthday.

This biography is from his Wikipedia page.

Constant Vanden Stock was the president and a player of Belgian football club R.S.C. Anderlecht. The stadium of this club is named after him. Constant Vanden Stock also served as coach of the Belgium national football team from 1958 to 1968. He is the father of another club president, Roger Vanden Stock. He is also behind the bribery of referee Emilio Guruceta Muro to throw the UEFA cup semi-final against Nottingham Forest in 1984. Vanden Stock managed the family brewery Belle-Vue, famous for its Kriek and Lambic, until he sold it to beer giant Interbrew, now InBev.

This tribute to Vanden Stock is from the 10th anniversary of his death in 2008, published by the RSCA in Belgium in 2018.

Son of brewer Philémon Vanden Stock and his wife Marie,  Constant Vanden Stock was born in Anderlecht on June 13, 1914, just before the start of the First World War. Ten years later, he began to play for the Mauve and Blancs, where he played only 52 matches in the first team between 1933 in 1938 due to serious injuries. He then joined the ranks of the neighbors of the Union Saint-Gilloise. Five years later, he put an end to his sports career and he focused on the development of Belle-Vue, his father’s brewery.

In the early 1950s, Constant Vanden Stock occupied a very first position at Sporting. He was there for three years responsible for recruiting young people. Constant was also the cadet and school coach. After a short stint as president of La Forestoise, he was appointed to the selection committee of URBSFA. Two years later, he became the only national team coach. Albert Roosens, the Anderlecht president at the time, wanted to bring him back to the RSCA, but Constant nevertheless chose the role of technical director at the Club Brugeois. A year later, in 1969, he returned to the capital, however. Constant became a member of management and also vice-president there, before finally taking over the helm as president in 1971.

It was the start of a long and successful period. In twenty-five years of presidency, Constant Vanden Stock managed to add many trophies to the prize list of our club. He celebrated ten Belgian champion titles, seven Belgian Cups, two Cup Winners’ Cups, a UEFA Cup and two European Super Cups. In addition, the old Émile Versé stadium was completely renovated between 1983 and 1991 to become a football stadium with boxes and  business seats , a great novelty. The enclosure was logically renamed the Constant Vanden Stock stadium to pay tribute to his work.

In 1996, Constant Vanden Stock decided to pass the baton to his son Roger, but he remained, at 82, obviously very attached to his club, as honorary president. In 2005, Constant’s health began to deteriorate, with balance problems which were followed by a heart attack. Constant Vanden Stock died on April 19, 2008, just before the centenary of his club, at the age of 93 years. Rest in peace, Mr. Constant.

This thorough history of Brasserie Belle Vue is from the website Lambic.Info:

Brasserie Belle-Vue has a long and sometimes controversial history of innovation, takeover, and survival among the lambic brewers and blenders. It was founded in 1913, by a café blender named Philémon Vandenstock (1886 – 1945). The owner of a bar in Brussels, Vandenstock, along with his wife, bought wort from various lambic breweries in the city and began blending fondgeuze for the establishment. Shortly after they began their blending business, World War I broke out leaving few resources to continue. Finally, in 1927, the Belle-Vue Café in Anderlecht became available. Vandenstock purchased the building as an outlet for his lambics; serving five other cafes in the area while also selling directly to customers. From 1927 onward, the blendery would market itself under the Belle-Vue name with a mention to Ph. Vandenstock usually visible somewhere on the branding.

The business flourished under Philémon, leading to the first brewery acquisition by Belle-Vue in 1943: Vos-Kina, a lambic brewery located in Sint-Jans-Molenbeek. The acquisition of the brewery came at a difficult time in Europe’s history, right in the middle of World War II. While many breweries were struggling through the war, Belle-Vue was growing. Now able to brew his own lambic, Vandenstock also brought his son Constant Vandenstock and his son-in-law Octave Collin Vandenstock into the business to help manage.[1] Sadly, Philémon was arrested by the occupying Nazi forces in 1944 and sent to the Neuengamme concentration camp where he remained until it was liberated in May of 1945. He died just one week after the camp’s liberation.

The journey of Belle-Vue’s slide into non-traditional lambic started immediately after the death of Philémon when his son Constant took over the business. Until then, Belle-Vue was producing only traditional fondgeuze; however, like many other lambic breweries at the time, Constant began to use artificial flavorings to adapt to the changing palates of Belgian lambic drinkers. Belle-Vue began sweetening, filtering, pasteurizing, and carbonating its gueuze so that it could be consumed more like a traditional European pale lager rather than a traditional lambic. Belle-Vue also was one of the first, if not the first, lambic breweries to move away from using the traditional 75cl bottles to using capped 25cl bottles. This provided an easy “one bottle for one glass” strategy and did away with specialty corkscrews needed for opening the larger bottles.

The journey to the top of the lambic world for Belle-Vue began in the 1949-1950 season when Belle-Vue began to send lambic across the country and into France and the Netherlands. Belle-Vue, who was at the time the only lambic brewery with filtered and pasteurized gueuze, managed to escape the heatwave that resulted in exploding bottles for the majority of the lambic brewers and blenders that season. Business was so good that the brewery went on to two more takeovers, taking over the Louis & Emile De Coster lambic brewery in 1952 and Timmermans in 1955.

Constant, who was always involved with the football leagues in Belgium and Europe brought his son, Roger, as well as Roger’s cousin Philipe, into the business in 1962. In 1969, Belle-Vue acquired two more breweries: De Boeck and Goossens, known together as Brasseries Unies (United Breweries). These two breweries together had already acquired Brasseries Brasserie de la Couronne (De Kroon), Espagne, De Coster-Heymans, and Vandenkerckhoven. Again in 1970 Belle-Vue acquired Brabrux, which had already acquired other well known lambic breweries De Keersmaeker, Vaan Haelen-Coche, Bécasse-Steppé, and Vandenperre. At this point, Belle-Vue controlled approximately 75% of the lambic market. De Neve was also taken over by Belle-Vue in 1975, which is now a set of luxury apartments in the old brewery building.

Belle-Vue was riding a wave of success that very few lambic breweries were achieving at the time, but to do this Belle-Vue needed the help of one brewery still bigger than them in Belgium: Artois. Belle-Vue partnered with Artois to help expand its brand in the export market. The cost of this was a 43% minority share for Artois in Belle-Vue, with Constant still remaining in charge of Belle-Vue. When Artois merged with Piedboeuf (most recognized as the brewer of Jupiler) in 1988 to create Interbrew, it effectively put an end to the Vandenstock family stake in Belle-Vue.

Today, Brasserie Belle-Vue exists under the AB-InBev umbrella and consistently puts out non-traditional, sweetened lambics for the masses. No longer producing a traditional lambic or gueuze, the final true-to-style Belle-Vue product was the Belle-Vue Sélection Lambic released in 1999. Belle-Vue beers are now produced at the brewery in St. Pieters-Leeuw located just outside the Brussels Capital Region in Flemish Brabant. Belle-Vue is not a member of HORAL.

Eoghan Walsh also has a nice overview of the legacy of the lambic brewery entitled “Monsieur Constant // How one brewer defined beer and football in Brussels for the 20th century.”

uc-davis-horse
Today is the 73rd birthday of Charlie Bamforth, who was the Anheuser-Busch Endowed Professor of Brewing Science at U.C. Davis (and was my teacher when I took the brewing short course there). His three most recent books should be on your must read list: In Praise of Beer, Beer Is Proof That God Loves Us and Grape vs. Grain. He’s a terrific advocate for beer and a great person. He was also kind enough to speak to beer appreciation class that I taught at Sonoma State University and our Beer Writers Guild symposium a few years ago in Philadelphia. Join me in wishing Charlie a very happy birthday.

Coming back from some beer judging in London a few summers ago, I randomly ended up on the same flight back to San Francisco with Charlie, in fact I sat behind him on the plane.

Historic Beer Birthday: John Hemrich

June 12, 2025 By Jay Brooks Leave a Comment

Bay-View

Today is the birthday of John Hemrich (June 12, 1823-August 24, 1896). He was born in Baden-Württemberg, Germany, trained as a brewer, and came to America when he was 25, and had breweries in New York, Iowa, Wisconsin, but eventually ended up in Washington state, where he founded the Bay View Brewery, which eventually merged with two other Seattle breweries to become the Seattle Brewing and Malting Co.

He’s also the father of Andrew Henrich, Alvin Hemrich, and Louis Hemrich, all of whom worked with other family members on a variety of brewery projects over the years. It’s a complicated story, but Gary Flynn at Brewery Gems is your best bet for understanding it all, and I recommend starting with his biography of John Hemrich.

Historic Beer Birthday: Carl von Linde

June 11, 2025 By Jay Brooks Leave a Comment

frig
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.”

Carl_von_Linde_1868

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.

eCopy, Inc.
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).

Building the first Linde ice machine

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.

linde-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.

horizontal-twostage-ammonia-compressor
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.

Dr.Carl-von-Linde-1925

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: Anton Ruh

June 11, 2025 By Jay Brooks Leave a Comment

bavarian-kentucky
Today is the birthday of Anton Ruh (June 11, 1845-November 26, 1925). Ruh was born in Germany, but made his way to America, settling in Kentucky. In 1889, he became the brewmaster of the Bavarian Brewing Co. of Covington, Kentucky, after Wilhelm Riedlin became the sole owner. He brewed there until prohibition began, and even though the brewery did reopen after repeal, he had passed away in 1925.

There isn’t a great deal of information about Anton Ruh, although there’s this brief mention from the North Kentucky Tribune:

One Covington family contributed greatly to the beer brewing heritage of Covington. German immigrant Anton Ruh was a long-time brew master at Bavarian Brewery. Under his leadership, the Bavarian brand gained a reputation across the Midwest. Anton’s son, Joseph Ruh, was associated with both Bavarian and Heidelburg Breweries. Joseph’s son, Carl Ruh, was a teacher at Covington Catholic High School, a Kentucky State Representative and Kenton County Sheriff.

It appears that Ruh may be front and center in this photo of the brewery workers from an unknown date.

And this history of the brewery is from “The Encyclopedia of Northern Kentucky,” edited by Paul A. Tenkotte, James C. Claypool:

Historic Beer Birthday: Prosper Cocquyt

June 9, 2025 By Jay Brooks

Today is the birthday of Prosper Cocquyt (June 9, 1900-October 22, 1954). He was born in Astène, Belgium, near Ghent, and is primarily famous for being an aviator.

Prosper-Cocquyt

Prosper Cocquyt was called “the uncrowned king of the airline pilots.” Shortly after learning to fly, in his early twenties, joined Sabena World Airlines in its inception, and opened several routes for them, including to the Belgian Congo. He flew for them for over 25 years, and was even “the favorite pilot of the Belgian royal family and the personal pilot of the kings, Albert I and Leopold III.” Flying Zone has a lengthy biography of Cocquyt, and so does another website.

He was married to Elza Timmermans, and they had two children, a boy and a girl. It’s possible she was part of the Timmermans brewing family, but I’m not sure. But there’s another reason he’s included here.

When World War I broke out, Cocquyt was only fourteen, and he had to abandon going to school and find work. He was hired by a brewery run by a friend of his father as a mechanic. He distinguished himself by his knowledge of mechanics, and so impressed his boss, at sixteen, he was named chief mechanic, and even received a degree in mechanical engineering and electrical engineering at 21, before abandoning working in brewing to begin his career as a pilot. As far as I could tell, he never looked back.

Beer Birthday: Todd Ashman

Today is also the birthday of Todd Ashman, who turns 65. Todd is originally from Santa Rosa, but spent a number of years brewing at Flossmoor Station near Chicago, and then short stints at Titletown Brewing in Green Bay, Wisconsin and with Brewers Supply Group. Several years ago, Todd moved back to California to take a position brewing with a then-new brewery in Truckee, Fifty Fifty Brewing, which he’d made into an amazing brewing powerhouse. Some health issues sidelined Todd for a time, and he’s moved back to Santa Rosa, but I did see him at our local Target during Covid and he’s working on a few things. Join me in wishing Todd a very happy birthday.
