Historic Beer Birthday: Samuel Whitbread

August 30, 2025 By Jay Brooks

whitbread
Today is the birthday of Samuel Whitbread (August 30, 1720-June 11, 1796). He founded a brewery with a few partners in 1742, but was the largest investor and retained control of the venture. In 1799 his brewery was renamed Whitbread & Co. Ltd. He was also “appointed High Sheriff of Hertfordshire for 1767–68 and elected Member of Parliament for Bedford in 1768, and held the seat until 1790.” The portrait of Samuel Whitbread below was painted by Joshua Reynolds.

Here is Peter Mathias’ biography from the Oxford Dictionary of National Biography:

Whitbread, Samuel (1720–1796), brewer and landowner, was born on 30 August 1720 at Cardington, near Bedford, the seventh of eight children and the youngest of five sons of Henry Whitbread (d. 1727) and his second wife, Elizabeth Read. The Whitbread family were of prosperous nonconformist yeoman stock, farming their own land and closely associated with leading Bedfordshire puritans. Whitbread’s father was receiver of the land tax for Bedfordshire, and his first wife was the daughter of John Ive, a London merchant. This gave Whitbread the advantage, through a half-brother, of a connection in the City when his widowed mother apprenticed him at the age of sixteen to John Wightman of Gilport Street, a leading London brewer, for the large fee of £300. He set up in business himself in December 1742 with two partners, Godfrey and Thomas Shewell, buying a small brewery at the junction of Old Street and Upper Whitecross Street and another brewhouse for pale and amber beers in Brick Lane, Spitalfields. Whitbread brought an inheritance of £2000 to the firm, plus the proceeds of a small family holding in Gloucestershire, and loans from friends and kinsmen in Bedfordshire. He became free of the Brewers’ Company on 8 July 1743. The partnership was valued at £14,016, owning the leases of 14 public houses, with further loans to publicans, and deployed 18 horses and almost 18,000 casks. However, this was the prelude to a dramatic new venture.

Godfrey Shewell withdrew from the partnership as Thomas Shewell and Samuel Whitbread borrowed more to buy the large site of the derelict King’s Head brewery in Chiswell Street in 1750. The new brewery was specifically for the single product porter, the basis for the vast brewing enterprises then being developed in London by Henry Thrale and Sir Benjamin Truman. It was named the Hind’s Head brewery after the Whitbread family coat of arms. From the outset Whitbread was the leading partner financially, solely responsible for management, and Shewell withdrew completely in 1761, Whitbread buying out his share for £30,000. Great expansion ensued, with such notable innovations as vast underground cisterns containing 12,000 barrels of porter, designed by John Smeaton, and benefiting from installation of only the second Boulton and Watt steam engine in London (Henry Goodwyn, also a brewer, had beaten him by a matter of months). Public renown came on 27 May 1787 with a royal visit to Chiswell Street—by the king and queen, three princesses, and an assembly of aristocrats in train—with James Watt on hand to explain the mysteries of his engine. In the year of Whitbread’s death, 1796, the brewery produced an unprecedented total of 202,000 barrels (that is, almost 30 million quart pots of porter).

Great investment in the brewery did not preclude Whitbread’s amassing a personal fortune and large estates. On his marriage in July 1757 to Harriet, daughter of William Hayton of Ivinghoe, Buckinghamshire, a leading London attorney, Whitbread began buying land in Cardington, the locality of his birth. His wife died in 1764, leaving him with an only son, Samuel Whitbread (the couple also had two daughters). Whitbread went on to buy the Bedwell Park estate in Hertfordshire in 1765, and he also owned London houses, first at St Alban’s Street, Westminster, and then at Portman Square (from 1778), together with a large house in Chiswell Street by the brewery. In 1795 shortly before his death he bought Lord Torrington’s Southill Park estate in Bedfordshire and immediately engaged the architect Henry Holland to rebuild the existing house. Whitbread had by this time accumulated a landed estate worth some £400,000.

Affluence brought higher social status and also Whitbread’s second marriage on 18 August 1769 to Lady Mary Cornwallis, younger daughter of Earl Cornwallis; but she died in 1770, giving birth to a daughter, Mary Grey (1770–1858). Whitbread became MP for Bedford in 1768, mainly, but certainly not always, supporting the tory interest until his son took over the seat in 1790. He was regarded as completely independent of the administration and spoke mainly on matters pertaining to the brewing industry, save that he was a firm advocate of the abolition of the slave trade.

Whitbread died on 11 June 1796 at Bedwell Park. He appointed his three senior clerks as his executors because his son was ‘a perfect stranger to the whole’ (Mathias, 309). Whitbread not only had his own portrait painted by Sir Joshua Reynolds, but he also commissioned Thomas Gainsborough, Gainsborough Dupont, and George Romney to paint portraits to hang in the library at Southill of all nine of his senior clerks and brewers, in recognition of their importance in managing the business. Unfortunately, in their very rich gilt frames the pictures had to observe the dissipation of the great fortune by the younger Samuel Whitbread as he pursued a costly social and parliamentary career, neglecting the brewery which had been the source of the family’s wealth and prestige.

An early history of the company from Encyclopedia.com:

Samuel Whitbread, at the age of 14, was sent to London by his mother in 1734 to become an apprentice to a brewer. Whitbread, raised as a Puritan, proved to be an extremely hard worker. In 1742, eight years after coming to London, he established his own brewery with a £2,000 inheritance and additional underwriting from John Howard, the renowned prison reformer. As the brewery became successful, Howard’s investment became more lucrative—it even led to a reciprocation of financial support by Whitbread for Howard’s reform movement.

By 1750 Whitbread had acquired an additional brewery located on Chiswell Street. At this time there were more than 50 breweries in London, but, despite intense competition, the Whitbread brewery expanded rapidly. By 1760 its annual output had reached 64,000 barrels, second only to Calvert and Company.

Whitbread was enthusiastic about new brewing methods. He employed several well-known engineers who helped to improve the quality and increase the production volume of the company’s stout and porter (a sweeter, weaker stout).

The Whitbread family had a long history of involvement in English politics. Samuel Whitbread’s forefathers fought with Oliver Cromwell’s Roundheads during the English Civil War and later developed a connection with the Bedfordshire preacher and author John Bunyan. Samuel Whitbread himself was elected to Parliament in 1768 as a representative of Bedford. His son, Samuel II, succeeded him in Parliament in 1790, and Whitbread descendants served in Parliament almost continuously until 1910.

Samuel Whitbread died in 1796.

Beer In Ads #5066: Old Dutch Lunch, Bock Beer, Ice Cream

August 29, 2025 By Jay Brooks

Last year I decided to concentrate on Bock ads. Bock, of course, may have originated in Germany, in the town of Einbeck. Because many 19th century American breweries were founded by German immigrants, they offered a bock at certain times of the year, be it Spring, Easter, Lent, Christmas, or what have you. In a sense they were some of the first seasonal beers. “The style was later adopted in Bavaria by Munich brewers in the 17th century. Due to their Bavarian accent, citizens of Munich pronounced ‘Einbeck’ as ‘ein Bock’ (a billy goat), and thus the beer became known as ‘Bock.’ A goat often appears on bottle labels.” And presumably because they were special releases, many breweries went all out promoting them with beautiful artwork on posters and other advertising.

Friday’s ad is for an Old Dutch Lunch, apparently consisting of Bock Beer and Ice Cream, which was published on August 29, 1919. It’s not mentioned which specific bock beer the Parlor Drug Store (who placed the ad) was serving, though it was apparently the “Coolest Place in Town.” It must have been near a military base since the ad also mentions they were in “Class A, as designated by the U.S. Army.” This ad ran in The Columbus Weekly Courier, of Columbus, New Mexico.

Historic Beer Birthday: Charles H. Wacker

August 29, 2025 By Jay Brooks

wacker-and-birk
Today is the birthday of Charles H. Wacker (August 29, 1856-October 31, 1929). Wacker’s family came from Württemberg Germany (though some sources claim he was from Switzerland), and he was 2nd generation American, having been born in Chicago, Illinois. His father Frederick, also a brewer, founded the Wacker and Birk Brewing and Malting Co. In 1882 or 83, Charles joined his father in the family business, and rose to prominence in Chicago throughout his life.

Charles-H-Wacker-1911

Here’s his short biography from Find-a-Grave:

He was a “mover and shaker” in the early days of Chicago. He was part of the Chicago Plan Commission formed to win acceptance of the famous Burnham Plan of 1909. He was a contemporary of Daniel Burnham and helped him promote his plan for the development of the city’s lakefront and system of parks. Lower and Upper Wacker Drive (two roads one on top of the other) in Chicago is named for him.

Here’s his Wikipedia entry:

Charles Henry Wacker, born in Chicago, Illinois, was a second generation German American who was a businessman and philanthropist. His father was Frederick Wacker, a brewer, who was born in Württemberg Germany. He was Vice Chairman of the General Committee of the Commercial Club of Chicago, and in 1909 was appointed Chairman of the Chicago Plan Commission by Mayor Busse. As Commission chairman from 1909 to 1926, he championed the Burnham Plan for improving Chicago. This work included addresses, obtaining wide publicity from newspapers, and publishing Wacker’s Manual of the Plan of Chicago (by Walter D. Moody) as a textbook for local schoolchildren.

Prior to serving on the Commission, Wacker was a Chicago brewer and the director of the 1893 Columbian Exposition held in Chicago.

As a businessman he was part of a consortium of Chicago brewers who underwrote the methods that facilitated the commercialization of refrigeration machines.

Wacker Drive, built as part of the Burnham Plan, and Charles H. Wacker Elementary School are named in his honor. The name Wacker is also attached to other institutions in Chicago, such as the Hotel Wacker.

Charles H. Wacker was educated at Lake Forest Academy (class of 1872) and thereafter at Switzerland’s University of Geneva.

wacker-and-birk

The Chicago brewery his father started was originally called Seidenschwanz & Wacker, and was located on Hinsdale, between Pine and Rush streets. It was founded in 1857, but the following year it became known as Wacker & Seidenschwanz, and was on N. Franklin Street. That version lasted until 1865. Beginning that same year, its name changed once again to the Frederick Wacker Brewery, and its address was listed as 848 N. Franklin Street, presumably in the same location as its predecessor. Sixteen years later, in 1882, it relocated to 171 N. Desplaines (now Indiana Street) and it became known as the Wacker & Birk Brewing & Malting Co. This is also when Charles joined his father’s business, when he would have been 26 years old. Just before prohibition the name was shortened to the Wacker & Birk Co., although it appears to have closed by 1920.

wacker-poster

Here’s one more biography, from the library at the University of Illinois at Chicago:

Wacker was born in 1856 to a German immigrant who owned a brewing and malting company. Although he worked as a real estate investor and bank director, Wacker eventually took over his father’s business. In civic affairs, Wacker was director of the Ways and Means Committee for the World’s Columbian Exposition of 1893. In 1909, Mayor Fred Busse appointed Wacker to the Chicago Plan Commission, a committee designed to convince residents to issue bonds and spend money on widening streets, improving sidewalks, and redeveloping parts of the city. During his tenure on the Commission, Wacker urged voters to approve the forest preserves referenda. Later, he served on the Forest Preserve Plan Committee. Chicago leaders rewarded Wacker by renaming a double-decker roadway after him. First proposed in the Burnham Plan and completed in the 1920s, Wacker Drive runs along the Chicago River in the Loop.

Thursday’s ad is for Graupner Bock Beer, which was published on August 28, 1933. This one was for the Robert H. Graupner Brewery of Harrisburg, Pennsylvania, which was originally founded in 1875 as Koenig & Bro. and was also often called the Centennial Brewery, though Graupner was usually in the name after 1893. They also mention two of the other beers, Graupner’s X-Tra Fine Beer and Silver Stock Lager. But what’s most curious about the ad is that most of it is taken up by the telling of one of the many origin stories of bock beer. This ad ran in The Harrisburg Telegraph, also of Harrisburg, Pennsylvania.

Wednesday’s poster is for Falken Schaffhauser’s Bock, and was published in 1934. This one was made for the Bierbrauerei Falken Schaffhausen, or Falcon Brewery, of Schaffhausen, Switzerland. The brewery was founded in 1799, and is still in business today, and is “considered the only independent brewery in the Schaffhausen region,” and is Switzerland’s 5th largest brewery. This one is for their Schaffhauser Bock and shows a group of protestors carrying signs, though in the end they’re just beer signs. It was created by Swiss artist Arnold Oechslin.

Historic Beer Birthday: Hans Adolf Krebs

August 25, 2025 By Jay Brooks

science
Today is the birthday of Hans Adolf Krebs (August 25, 1900-November 22, 1981). He was a German-born British physician and biochemist. He was the pioneer scientist in study of cellular respiration, a biochemical pathway in cells for production of energy. He is best known for his discoveries of two important chemical reactions in the body, namely the urea cycle and the citric acid cycle. The latter, the key sequence of metabolic reactions that produces energy in cells, often eponymously known as the “Krebs cycle,” earned him a Nobel Prize in Physiology or Medicine in 1953. And it’s the Krebs cycle that is his relation to brewing, as it’s also known as the respiratory phase, the second aerobic state of the fermentation process immediately following the lag period.

krebs-signature

Here’s a description of the Krebs cycle from Life Fermented:

The Krebs cycle, also known as the tricarboxylic acid (TCA) cycle or the citric acid cycle, is a circular and repeating set of reactions which requires oxygen. In beer making, this would occur in the first stage of fermentation when the yeast is pitched into a well aerated wort, and carries on until all oxygen is used up.
Pyruvate (are you tired of this word yet?) is first converted to acetyl-CoA (pronounced “Co-A”) in the following reaction:

pyruvate + 2 NAD+ + CoA-SH → acetyl-CoA + CO2 + NADH, with the help of the pyruvate dehydrogenase (PDH) complex. Note that this is the first time CO2 is produced, and yet more NADH is generated.

This acetyl-CoA then enters into a cycle of reactions which nets two molecules of CO2, one GTP (guanosine triphosphate, another unit of energy equivalent to ATP), three NADH, and one FADH2 (flavin adenine dinucleotide, which functions similarly to NADH). After the cycle completes, another acetyl-CoA molecule enters and the cycle repeats itself.

But wait, this just made more NADH, and we need to regenerate NAD+ so glycolysis can continue. Both the NADH and FADH2 now donate their electrons to a process called the electron transport chain/ oxidative phosphorylation. The result is a return of NAD to the NAD+ state, and a large amount of ATP cellular energy.

Because the Krebs cycle is so efficient at producing ATP energy units, this is the yeast’s preferred pathway. But, you’ll notice a rather conspicuous absence: ethanol. This is only formed in the absence of oxygen.

NPG x88332; Sir Hans Adolf Krebs

Here’s a biography of Krebs, from the Nobel Prize website:

Sir Hans Adolf Krebs was born at Hildesheim, Germany, on August 25th, 1900. He is the son of Georg Krebs, M.D., an ear, nose, and throat surgeon of that city, and his wife Alma, née Davidson.

Krebs was educated at the Gymnasium Andreanum at Hildesheim and between the years 1918 and 1923 he studied medicine at the Universities of Göttingen, Freiburg-im-Breisgau, and Berlin. After one year at the Third Medical Clinic of the University of Berlin he took, in 1925, his M.D. degree at the University of Hamburg and then spent one year studying chemistry at Berlin. In 1926 he was appointed Assistant to Professor Otto Warburg at the Kaiser Wilhelm Institute for Biology at Berlin-Dahlem, where he remained until 1930.

In I930, he returned to hospital work, first at the Municipal Hospital at Altona under Professor L. Lichtwitz and later at the Medical Clinic of the University of Freiburg-im-Breisgau under Professor S. J. Thannhauser.

In June 1933, the National Socialist Government terminated his appointment and he went, at the invitation of Sir Frederick Gowland Hopkins, to the School of Biochemistry, Cambridge, where he held a Rockefeller Studentship until 1934, when he was appointed Demonstrator of Biochemistry in the University of Cambridge.

In 1935, he was appointed Lecturer in Pharmacology at the University of Sheffield, and in 1938 Lecturer-in-Charge of the Department of Biochemistry then newly founded there.

In 1945 this appointment was raised to that of Professor, and of Director of a Medical Research Council’s research unit established in his Department. In 1954 he was appointed Whitley Professor of Biochemistry in the University of Oxford and the Medical Research Council’s Unit for Research in Cell Metabolism was transferred to Oxford.

Professor Krebs’ researches have been mainly concerned with various aspects of intermediary metabolism. Among the subjects he has studied are the synthesis of urea in the mammalian liver, the synthesis of uric acid and purine bases in birds, the intermediary stages of the oxidation of foodstuffs, the mechanism of the active transport of electrolytes and the relations between cell respiration and the generation of adenosine polyphosphates.

Among his many publications is the remarkable survey of energy transformations in living matter, published in 1957, in collaboration with H. L. Kornberg, which discusses the complex chemical processes which provide living organisms with high-energy phosphate by way of what is known as the Krebs or citric acid cycle.

Krebs was elected a Fellow of the Royal Society of London in 1947. In 1954 the Royal Medal of the Royal Society, and in 1958 the Gold Medal of the Netherlands Society for Physics, Medical Science and Surgery were conferred upon him. He was knighted in 1958. He holds honorary degrees of the Universities of Chicago, Freiburg-im-Breisgau, Paris, Glasgow, London, Sheffield, Leicester, Berlin (Humboldt University), and Jerusalem.

He married Margaret Cicely Fieldhouse, of Wickersley, Yorkshire, in 1938. They have two sons, Paul and John, and one daughter, Helen.

And in the Microbe Wiki, on a page entitled “Saccharomyces cerevisiae use and function in alcohol production,” under a section called “Fermentation of alchohol,” the Krebs cycle is placed in its portion in the fermentation process:

Saccharomyces cerevisiae is able to perform both aerobic and anaerobic respiration. The process begins with the yeast breaking down the different forms of sugar in the wort. The types of sugars typically found in wort are the monosaccharides glucose and fructose. These sugars contain a single hexose, which is composed of 6 carbon atoms in the molecular formula C6H12O6. Disaccharides are formed when two monosaccharides join together. Typical disaccharides in the wort are galactose, sucrose, and maltose. The third type of fermentable sugar in the wort is a trisaccharide. This trisaccharide is formed when three monosccharides join together. Maltotriose is the trisaccharide commonly found in the wort and is composed of three glucose molecules. The wort does contain other sugars such as dextrins but it is not fermentable by yeast10. These dextrins contain four monosaccarides joined together. In order for the yeast to use the disaccharides and trisaccharides they first must be broken down to monosaccharides. The yeast does this by using different enzymes both inside and outside the cell. The enzyme invertase is used to break down sucrose into glucose and fructose. The invertase catalyzes the hydrolysis of the sucrose by breaking the O-C (fructose bond). The other enzyme used is maltase, which breaks down maltose and maltotriose into glucose inside the cell. The enzyme does this by catalyzing the hydrolysis of the sugars by breaking the glycosidic bond holding the glucose molecules together.

Once the sugars are broken down into monosaccharides the yeast can use them. The primary step is called glycolysis. In this process the glucose is converted to pyruvate using different enzymes in a series of chemical modifications. The electrons from glucose end up being transferred to energy carrying molecules like NAD+ to form NADH. ATP is also formed when phosphates are transferred from high-energy intermediates of glycolysis to ADP. In the presence of oxygen aerobic respiration can occur. This occurs in the mitochondria of the yeast. The energy of the pyruvate is extracted when it goes through metabolic processes like the Krebs cycle. The products of this type of metabolism are ATP, H2O, and CO2. However if there is no oxygen present and an abundance of sugars, as in the wort, the yeast undergo alcoholic fermentation. This type of metabolism yields much smaller amounts of energy when compared to aerobic respiration. However, because of the large supply of sugars from the different grains the wort is a very good environment for fermentative growth. The alcoholic fermentation begins with the two pyruvate acquired from glycolysis. These two pyruvate are decarboxylated by pyruvate decarboxylase to form two acetaldehydes and CO2. The CO2 is the gas that is observed during fermentation as bubbles that float to the top of the wort creating the kräusen or beer head, the foam that is very characteristic of a freshly poured beer. Pyruvate decarboxylase is a homotetramer meaning it contains four identical subunits. This also means that is has four active sites. The active sites are where the pyruvate reacts with the cofactors thiamine pyrophosphate (TPP) and magnesium to remove the carbon dioxide9. The final step to form alcohol is the addition of a hydrogen ion to the aldehyde to form ethanol. This hydrogen ion is from the NADH made during glycolysis and converts back to NAD+. The ethanol is originally believed to serve as an antibiotic against other microbes. This form of defense ensures that bacteria do not grow in the wort, thus ruining the beer with off flavors. However recently with the boom of craft beer different bacteria have been purposefully added to create what is known as sour beer. The sour taste comes from the waste products of the bacteria.

Historic Beer Birthday: August Uihlein

August 25, 2025 By Jay Brooks

schlitz-globe
Today is the birthday of August Uihlein (August 25, 1842-October 11, 1911). He was born in Wertheim am Main, Baden, Germany. He came to the U.S. with his grandfather and August was educated as a brewer in the U.S., working initially for the Uhrig Brewery in St. Louis. In 1867, he returned to Milwaukee, Wisconsin, where his grandfather had settled, and “joined what was now the Joseph Schlitz Brewing Company, the same brewery that had been founded by his uncle August Krug in the 1840s (Krug’s widow, Anna Maria, had married Joseph Schlitz in 1858).”

On the death of Schlitz in 1875, control of the firm passed into the hands of Uihlein and his brothers. When Mrs. Schlitz died in 1887, the Uihlein brothers acquired complete ownership of the corporation. Uihlein was secretary and chairman of the board (1874–1911). He was also actively involved in banking, real estate, and many other Milwaukee businesses.

 

Here’s a biography of August Uihlein from Find-a-Grave:

Brewer and business executive. He was the first of the Uihlein dynasty that owned and operated Joseph Schlitz Brewing Co. over the years. Born Georg Carl August Ühlein, son of Josef Benedikt Ühlein and Katherina Krug, in Wertheim am Main, Baden, Germany. At age eight he endured a rough immigration on the way to Milwaukee, Wisconsin, in 1850, traveling with his grandfather, Georg Krug. He survived the mid-Atlantic fire and sinking of the S.S. Helene Schlomann, during which his grandfather managed to save him and $800 in gold that was subsequently used to expand his uncle August Krug’s brewery and to hire a bookkeeper, Joseph Schlitz. He attended Milwaukee’s German-English Academy, then studied at St. Louis University in Missouri (1855 to 1857). His uncle, August Krug, died in 1856 and Schlitz became the manager of the brewery and two years later married Krug’s widow and changed the name to Joseph Schlitz Brewing Co. In 1858, at age 16, Uihlein convinced Schlitz to hire him as a bookkeeper after only 60 days training in the subject in St. Louis. August proposed to take a company inventory and revamp the brewery’s accounting system from single to double-entry bookkeeping. While holding down a full-time job (age 17) at the Second Ward Savings Bank (now First Wisconsin) without salary, he applied this training to the brewery’s accounting during evenings. For his efforts at the bank, he received a gold pen from Valentine Blatz after a year of service. He then worked the Uhrig Brewery in 1860 in St. Louis (the Uhrig family had a summer home in Milwaukee) as a bookkeeper, collector, and shipping clerk for $20 a month and two years later, shortly before his 20th birthday, he was promoted to the position of general manager. Returning to Milwaukee in 1867, he became the bookkeeper for the Joseph Schlitz brewery, and on the death of Schlitz in 1875, management control of the firm passed into the hands of him and his brothers, all nephews of the brewery’s original founder, August Krug. Along with his brothers Henry and Edward, he continued the business strategies initiated by Schlitz. The company developed a system of agencies across the United States to sell beer, and developed its own vast rail distribution network. When Mrs. Schlitz died in 1887, the Uihlein brothers acquired complete ownership of the enterprise. From a ranking of tenth largest US brewer in 1877, their national marketing plan propelled the company to third by 1895. Sitting among the top three breweries was little comfort when prohibition came about. The company met the challenge as did others, restructuring the brewery as Joseph Schlitz Beverage Co. to produce near beer, yeast, soft drinks, malt syrup and a chocolate candy named “Eline” (a phonetic play on the family name). Returning to brewing in 1933, the company launched an acquisition plan and new construction that led them to second and then first place in US beer production. For the next 40 the years the company would remain near the top and at one point was ranked as the largest in the world. August Uihlein was Schlitz company secretary from 1874 and also chairman of the board from 1880 until his death in 1911, and was prominently identified with banking, real estate, and many other Milwaukee enterprises. Interested in racing horses, he maintained a large stock farm near Kenosha and was the owner of the famous trotting-horse champion, “Harvester.” Noted for his local philanthropy, he donated large sums to the German-English Academy and to the Milwaukee Public Library. He died while visiting in Germany.

Historic Beer Birthday: Louis Wiegand

August 24, 2025 By Jay Brooks

Today is the birthday of Louis Wiegand (August 24, 1840-March 2, 1912). He was born in Frankfort, Germany, he emigrated to America when he was 27, in 1867. He was initially in the meat business but in 1878, along with partners Carl Durr and William Wagner, he founded the Oswego German Brewing Co. in Oswego, New York. A few years later, in 1882, he bought out his partners, and renamed if the Wiegand Brewing Co. and then the Louis Wiegand Brewing Co. When his sons joined him in the business in 1896 it became known as Louis Wiegand & Son. It was closed by prohibition in 1916 and never reopened.

This is his obituary, from the Oswego Daily Times, for Monday, March 4, 1912:

The death of Louis Wiegand senior member of L Wiegand & son brewers, which occurred at his home, No 166 East Second street, Saturday evening at 4:45 o’clock, will be received with sorrow by citizens generally. Mr. Wiegand had been in failing health since last May and for several months had been confined to his home. Born in Wirthheina, near Frankfort, Germany, in 1840, Mr. Wiegand came to Oswego in 1867, He engaged successfully in the meat business in East Bridge street for several years. In 1882, Mr. Wiegand organized the Germania Brewing Company and shortly thereafter took over the business, which he has successfully conducted ever since. Deeply interested in the St. Peter’s Cemetery association and one of its organizers, Mr. Wiegand was zealous in promoting it. He had been president of the society for several years. When It was desired to acquire more property for the extension of the cemetery, the funds on hand were not sufficient. Mr. Wiegand purchased the property and sold it to the association without profit to himself. He was a constant visitor to the cemetery and gave much of his time to plans for beautifying it.

Mr. Wiegand’s first wife died several years ago. He is survived by his second wife, formerly Miss Catherine Stoke; one son, Louis X, and a sister, Mrs. Margaret Cook, all of Oswego. The funeral will be held tomorrow morning from his home and at St Peter’s church.

Unfortunately, apart from his obituary, there was almost nothing else I could find about him, his sons or his brewery, not even any photos or breweriana.
