Historic Beer Birthday: Emile A.H. Seipgens

August 16, 2025 By Jay Brooks

netherlands
Today is the birthday of Emile Anton Hubert Seipgens (August 16, 1837-June 25, 1896). Seipgens was born in Roermond, the Netherlands. He was the son of a brewer, and after school and some failed jobs, joined his father at the brewery in 1856. By 1859, he was running the brewery along with his brother. But apparently he wasn’t happy there, and in 1874 decided to pursue his dream of becoming a writer. Throughout his life, he wrote poetry, novels, plays and much more.

Seipgens

Here’s a translated biography of his literary career, from Literary Zutphen:

Emile (Anton Hubert) Seipgens, born August 16, 1837 in Roermond, from 1876 until 1883 teacher of German at the Rijks HBS in Zutphen. He founded a literary reading companion for his disciples and was a member of the “Circle of scientific maintenance. He lived Nieuwstad A128-2. Seipgens was an outspoken Limburg author. His work – theater, novels and novellas village – is invariably located in Limburg, and sometimes – his songs – even written in Limburg dialect. Some of his best known and most read titles he wrote in his Zutphense period: The chaplain Bardelo (1880), from Limburg. Novellas and Sketches (1881). In this period made ​​Seipgens, who was first trained to be a priest, then was brewer, then teacher, to eventually become a writer, definitively separated from the Catholic Church. He started on the assembly line to write stories, which he published in magazines such as The Guide , Netherlands and Elsevier . One of those stories, Rooien Hannes , had worked to folk drama and staged by the Netherlands Tooneel great success. Later titles are: In and around the small town (1887), along Maas and Trench (1890), The Killer Star (1892), Jean, ‘t Stumpke, Hawioe-Ho (1893), The Zûpers of Bliënbèèk (1894) and A wild Rosary (1894). In 1892 Seipgens secretary of the Society of Dutch Literature in Leiden, and in that place he died 1896. Posthumously published yet his novel on June 25, Daniel (1897) and the beam A Immortellenkrans (1897). Seipgens, which is one of the earliest naturalists of the Netherlands became completely into oblivion, until the late 70s of the last century actually was a small revival. Which among other things led to reprint the novel The chaplain Bardelo and stories in and around the small town , and to the publication of his biography, written by Peter Nissen: Emile Anton Hubert Seipgens (1837-1896). Of brewer’s son to literary (1987), and the placing of a memorial stone at Seipgens birthplace. But this revival was short-lived. If Emile Seipgens remembered voortleeft, it will have to be on the legend of the rovershoofdman Johann Bückler based ‘operabouffe’ Schinderhannes (1864), which to this day in Roermond is staged!

And here’s another account from “The Humour of Holland,” published in 1894.

Charles Bukowski On Drinking

August 16, 2025 By Jay Brooks

Today’s is the birthday of Henry Charles Bukowski (August 16, 1920 – March 9, 1994).

He “was a German-American poet, novelist, and short story writer. His writing was influenced by the social, cultural, and economic ambience of his adopted home city of Los Angeles. Bukowski’s work addresses the ordinary lives of poor Americans, the act of writing, alcohol, relationships with women, and the drudgery of work. The FBI kept a file on him as a result of his column Notes of a Dirty Old Man in the LA underground newspaper Open City.

Bukowski published extensively in small literary magazines and with small presses beginning in the early 1940s and continuing on through the early 1990s. He wrote thousands of poems, hundreds of short stories and six novels, eventually publishing over sixty books during the course of his career. Some of these works include his Poems Written Before Jumping Out of an 8 Story Window, published by his friend and fellow poet Charles Potts, and better-known works such as Burning in Water, Drowning in Flame. These poems and stories were later republished by John Martin’s Black Sparrow Press (now HarperCollins/Ecco Press) as collected volumes of his work. As noted by one reviewer, “Bukowski continued to be, thanks to his antics and deliberate clownish performances, the king of the underground and the epitome of the littles in the ensuing decades, stressing his loyalty to those small press editors who had first championed his work and consolidating his presence in new ventures such as the New York Quarterly, Chiron Review, or Slipstream.”

In 1986, Time called Bukowski a “laureate of American lowlife”. Regarding his enduring popular appeal, Adam Kirsch of The New Yorker wrote, “the secret of Bukowski’s appeal … [is that] he combines the confessional poet’s promise of intimacy with the larger-than-life aplomb of a pulp-fiction hero.”

During his lifetime, Bukowski received little attention from academic critics in the United States, but was better received in Europe, particularly the UK, and especially Germany, where he was born. Since his death in March 1994, Bukowski has been the subject of a number of critical articles and books about both his life and writings.

He wrote about his drinking quite a bit in poems, short stories and in legend. Below is one of his more memorable quotes:

But that’s just the tip of the iceberg, so to speak. Drinking was a favorite topic of Bukowski and his writings on the subject were collected into a single volume entitled “Charles Bukowski On Drinking” in 2019. Here’s a few gems from that volume:

From “Charles Bukowski Answers 10 Easy Questions”

“Question: What would you say is the best brand of American beer on the market today?

Bukowski: Well, that’s a bit difficult. Miller’s is the easiest on my system but each new batch of Miller’s seems to taste a bit worse. Something is going on there that I don’t like. I seem to be gradually going over to Schlitz. And I prefer beer in the bottle. Beer in the can definitely gives off a metallic taste. Cans are for the convenience of storekeepers and breweries. Whenever I see a man drinking out of a can I think, “now there is a damn fool.” Also, bottled beer should be in a brown bottle. Miller again errs in putting the stuff into a white bottle. Beer should be protected both from metal and from light.

Of course, if you have the money, it’s best to go up the scale and get the more expensive beers, imported or better-made American. Instead of a dollar 35 you have to go a dollar 75 or 2 and quarter and up. The taste is immediately noticeable. And you can drink more with less hangover. Most ordinary American beer is almost poison, especially the stuff that comes out of the spigots at racetracks. This beer actually stinks, I mean, to the nose. If you must buy a beer at the racetrack it is best to let it sit for 5 minutes before drinking it. There is something about the oxygen getting in there that removes some of the stink. The stuff is simply green.

Beer was much better before World War 2. It had tang and was filled with sharp little bubbles. It’s wash now, strictly flat. You just do the best you can with it.

Beer is better to write with and talk with than whiskey. You can go longer and make more sense. Of course, much depends upon the talker and the writer. But beer is fattening, plenty, and it lessens the sex drive, I mean, both the day you are drinking it and the day after. Heavy drinking and heavy loving seldom go hand in hand after the age of 35. I’d say a good chilled wine is the best way out and it should be drank slowly after a meal, with just perhaps a small glass before eating.

Heavy drinking is a substitute for companionship and it’s a substitute for suicide. It’s a secondary way of life. I dislike drunks but I do suppose I take a little drink now and then myself. Amen.”

brewed and filled by … (1964)

“everything
in my beercan hand
is sad,
the dirt is even
sad
under my fingernails,
and this hand
is like the hand of a
machine
and yet
it is not—
it curves itself completely
(an effort containing magic)
around the
beercan
in a movement the same as
roots
pounding a gladiola
up into the sun of air,
and the beer
goes into me.”

beerbottle (1974)

“a very miraculous thing just happened:
my beerbottle flipped over backwards
and landed on its bottom on the floor,
and I have set it upon the table to foam down,
but the photos were not so lucky today
and there is a small slit along the leather
of my left shoe, but it’s all very simple:
we cannot acquire too much: there are laws
we know nothing of, all manner of nudges
set us to burning or freezing; what sets
the blackbird in the cat’s mouth
is not for us to say, or why some men
are jailed like pet squirrels
while others nuzzle in enormous breasts
through endless nights—this is the
task and the terror, and we are not
taught why. still, it’s lucky the bottle
landed straightside up, and although
I have one of wine and one of whiskey,
this forsooths, somehow, a good night,
and perhaps tomorrow my nose will be longer:
new shoes, less rain, more poems.”

The Bukowski Tapes (1985)

“I think a man can keep on drinking for centuries, he’ll never die; especially wine and beer . . . I like drunkards, because drunkards, they come out of it, and they’re sick and they spring back, they spring back and forth . . . If you gotta be anything, be an alcoholic. If I hadn’t been a drunkard, I probably would have committed suicide long ago. You know, working the factories, the eight hour job. The slums. The streets. You work a god damn lousy job. You come home at night, you’re tired. What are you gonna do, go to a movie? Turn on your radio in a three dollar a week room? Or are you gonna rest up and wait for the job the next day, for $1.75 an hour? Hell, no! You’re gonna get a bottle of whiskey and drink it. And go down to a bar and maybe get in a fist fight. And meet some bitch, something’s going on. Then you go to work the next day, and do your simple little things, right? . . . Alcohol gives you the release of the dream without the deadness of drugs. You can come back down. You have your hangover to face. That’s the tough part. You get over it, you do your job. You come back. You drink again. I’m all for alcohol. It’s the thing.”

beer (1976)

“I don’t know how many bottles of beer
I have drunk while waiting for things
to get better.
I don’t know how much wine and whiskey
and beer
mostly beer
I have drunk after
splits with women—
waiting
for the phone to ring
waiting for the sound of footsteps,
and the phone never rings
until much later
and the footsteps never arrive
until much later
when my stomach is coming up
out of my mouth
they arrive as fresh as spring flowers:
‘what the hell have you done to yourself?
it will be 3 days before you can fuck me!’

the female is durable
she lives seven and one half years longer
than a man, and she drinks very little beer
because she knows it’s bad for the
figure.

while we are going mad
they are out
dancing and laughing
with horny cowboys.

well, there’s beer
sacks and sacks of empty beer bottles
and when you pick them up
the bottles fall through the wet bottom
of the paper sacks
rolling
clanking
spilling grey wet ash
and stale beer,
or the sacks fall over at 4 A.M.
in the morning
making the only sound in your life.

beer
rivers and seas of beer
beer beer beer
the radio singing love
songs
as the phone remains silent
and the walls stand
straight up and down
the beer is all there is.”

Historic Beer Birthday: Johan Kjeldahl

August 16, 2025 By Jay Brooks

carlsberg-crown
Today is the birthday of Johan Gustav Christoffer Thorsager Kjeldahl (August 16, 1849-July 18, 1900) He was a Danish chemist who developed a method for determining the amount of nitrogen in certain organic compounds using a laboratory technique which was named the Kjeldahl method after him.

Kjeldahl worked in Copenhagen at the Carlsberg Laboratory, associated with Carlsberg Brewery, where he was head of the Chemistry department from 1876 to 1900.

He was given the job to determine the amount of protein in the grain used in the malt industry. Less protein meant more beer. Kjeldahl found the answer was in developing a technique to determine nitrogen with accuracy but existing methods in analytical chemistry related to proteins and biochemistry at the time were far from accurate.

Haslund_Johan_Kjeld
A painting by Otto Haslund of Johan Kjeldahl.

His discovery became known as the Kjeldahl Method

Kjeldahl's_distillation

The method consists of heating a substance with sulphuric acid, which decomposes the organic substance by oxidation to liberate the reduced nitrogen as ammonium sulphate. In this step potassium sulphate is added to increase the boiling point of the medium (from 337 °C to 373 °C) . Chemical decomposition of the sample is complete when the initially very dark-coloured medium has become clear and colourless.

The solution is then distilled with a small quantity of sodium hydroxide, which converts the ammonium salt to ammonia. The amount of ammonia present, and thus the amount of nitrogen present in the sample, is determined by back titration. The end of the condenser is dipped into a solution of boric acid. The ammonia reacts with the acid and the remainder of the acid is then titrated with a sodium carbonate solution by way of a methyl orange pH indicator.

In practice, this analysis is largely automated; specific catalysts accelerate the decomposition. Originally, the catalyst of choice was mercuric oxide. However, while it was very effective, health concerns resulted in it being replaced by cupric sulfate. Cupric sulfate was not as efficient as mercuric oxide, and yielded lower protein results. It was soon supplemented with titanium dioxide, which is currently the approved catalyst in all of the methods of analysis for protein in the Official Methods and Recommended Practices of AOAC International.

And Velp Scientifica also has an explanation of his method, which is still in use today.

Historic Beer Birthday: Charles D. Goepper

August 15, 2025 By Jay Brooks

Today is the birthday of Charles D. Goepper (August 15, 1860-June 7, 1909). In 18990, he was elected Secretary of the Phoenix Brewery of Louisville, Kentucky. The brewery was founded in 1859 as the Philip Zang Brewery, but became known as the Phoenix Brewery just two years later, in 1861, but closed in 1916 due to prohibition.

Here is Goepper’s obituary from the American Brewers’ Review:

Historic Beer Birthday: Adam Eulberg

August 15, 2025 By Jay Brooks

eulberg-bros

Today is the birthday of Adam Eulberg (August 15, 1835-May 20, 1901). He was born in Nassau, Germany but moved to Portage, Wisconsin with his family when he was 19, in 1854. In 1884 he and his brother Peter bought the City Brewery, which had been founded in 1852 by Carl Haertel. His brother Peter passed away suddenly shortly thereafter and Adam carried on the business alone, at least until his two sons were old enough to join him. Adam and Peter renamed the brewery Eulberg Bros. Brewery, but Adam’s family changed it to the Eulberg Brewing Co. in 1907. They survived prohibition making soda, and resumed beer production after repeal, but the Eulbergs sold the business in 1944. It closed for good in 1958.

Adam-Eulberg

This is Eulberg’s obituary from the American Brewers’ Review:

Adam-Eulberg-obit

The Eulberg Brewery before he bought it, in 1880.

This short history of the brewery is from the Wisconsin Historical Society:

Milwaukee dominated Wisconsin’s early brewing industry, but successful breweries were found in communities throughout the state. In 1852, German immigrant Carl Haertel began producing beer in Portage, Wisconsin. In 1884, brothers Adam and Peter Eulberg, also originally from Germany, acquired the Haertel Brewery. The Eulberg Brewing Company remained in the family until 1944 and shut its doors permanently in 1958.

Historic Beer Birthday: Christian Benjamin Feigenspan

August 15, 2025 By Jay Brooks

feigenspan
Today is the birthday of Christian Benjamin Feigenspan (August 15, 1844-April 10, 1899). He was born in Thuringia, Germany but moved his family to New Jersey and founded the C. Feigenspan Brewing Company of Newark in 1875, though at least one source says 1868. When he died in 1899, his son Christian William Feigenspan took over management of the brewery, which remained in business through prohibition, but was bought by Ballantine in 1943.

Christian-Benjamin-Feigenspan

There’s surprisingly little biographical information about Christian Benjamin Feigenspan, but here’s some history of his brewery:

In 1875 the Christian Feigenspan Brewing Company was founded at 49 Charlton St., at the former Laible brewery where he had previously been a superintendent. He would also marry Rachel Laible.

In 1878, he reportedly built a brewery on Belmont Street, and as late as 1886 a facility at 54 Belmont would be listed as the “Feigenspan Bottling Establishment”.

In 1880, Christian Feiganspan took over the Charles Kolb lager beer brewery (founded 1866) on Freeman Street. (Altho’, an 1873 map of Newark shows the property owned by a “Lenz Geyer Company”. There was a “Geyer” who was another Newark brewer who owned an “Enterprise Brewery” on Orange St.)

An 1884 fire would, reportedly, burn the brewery to the ground for a loss of $300,000.

By 1909, the firm would be advertising that “…Feigenspan Breweries are the largest producers of Ale in the United States!” (click on barrel above for text of ad) in an apparent dig at their much larger next door neighbor, P. Ballantine & Sons. Ballantine’s Lager Beer sales having by then accounted for 3/4 of their total production.

Possibly because of WWI era restrictions on the allowable alcohol level of beer (set at a mere 2.75%), Feigenspan entered into Prohibition with 4,000 barrels of aging ale in its cellar. In 1927, the ale would make the news as they tried to sell it. One story in July had it going to Heinz in Pittsburgh to be made into malt vinegar, but follow up articles say that in early November the ale was simply dumped into the sewer “…and thence into the Passaic River”.

Sadly, it would not be the first beer dumped by Feigenspan, which had one of the first four licenses to brew “medicinal beer” at the start of Prohibition. “Medicinal beer” was soon outlawed by the “Anti-Beer” law, and the brewery had to dump 600 cases of “real beer” (4.5% alcohol) in March of 1922.

Historic Beer Birthday: Eugene L. Husting

August 14, 2025 By Jay Brooks

eugene-husting

Today is the birthday of Eugene Louis Husting (August 14, 1848-November 27, 1916). He was born in Luxembourg, Germany, but came to the U.S. when he was only five, and settled with his family in Wisconsin. In 1877, he founded the Eugene L. Husting Brewery. In 1900, they changed its name to the E. L. Husting Co. Brewery, but it was closed due to prohibition in 1918. They appear to have concentrated on Weiss beer, and may have also been known as the E.L. Husting Weiss Beer Brewery. After repeal, the brewery never returned to brewing beer, instead concentrating on soda. The soda company closed in 1970.

This obituary of Husting is from the American Brewers’ Review:

Eugene-Husting-obit
husting-brewery-montage

This account of the brewery’s history is from the Blog, The Distant Mirror:

One other historic Milwaukee brewery that focused primarily on brewing wheat-based beer was Eugene Louis Husting.  Like many brewers before and after him, Eugene began as a brewer at the Northwestern Brewery, which was owned by Phillip Altpeter.  After marrying Phillip’s daughter Bertha in 1872, E.L. Husting opened his own weiss beer brewery and soda factory on the east side of 5th St. between Cherry St. and Vliet St. in 1877.  By 1884 Husting was brewing weiss beer in an 8 barrel brew kettle and selling the product in stoneware bottles.  In 1897 the Husting Brewery expanded inventory to include ginger ale, soda water, cream and orange soda, raspberry wine, and cider. As a result of prohibition (1920-1933), brewing beer discontinued and instead soda was exclusively produced.  Following prohibition the company evolved into a beer and soda distributor until 1970 when the plant shut down.  Today, the main building is still intact and is now considered the oldest standing complete brewery in Milwaukee.

Husting-bottle-ceramic

And this account of the brewery is by Kevin M Cullen in an article in Brewery History entitled “Rediscovering Milwaukee’s historic breweries: Part I: Milwaukee’s downtown breweries.”

Soon it was on to the oldest complete standing brewery structure in Milwaukee, the EL. Husting Brewery, whose name is still embossed along an upper cornice of the cream city brick building, which inci- dentally is now home to Great Lakes Archaeological Research Center, a former employer of mine. This brewery and soda factory was established by Eugene Louis Husting in 1877 on the eastside of 5th Street between Cheery Street and Vliet Street In 1884 EL Husting was brewing weiss beer in an eight-barrel brew kettle and bottling in stoneware bottles. He continued to brew sodas and beer here until he died in 1916, after which sodas became the primary bever- age of production during prohibition. Following Prohibition in 1933 the facility became a distribution plant for beer and liquor until it shut down in 1970.

Beer Birthday: Brandon Hernández

August 14, 2025 By Jay Brooks


Today is the 49th (maybe) birthday of Brandon Hernández, who is a Brewing Industry Contributor at The San Diego Union-Tribune and also stays busy with the San Diego Beer News, as a Craft Beer Correspondent at FOX 5 San Diego, Co-Host at The Indie Beer Show, Beer To The Rescue, and Food & Beverage Editor / San Diego On-Tap Host at Ranch & Coast Magazine. He also used to bethe Chief Marketing Officer for Societe Brewing, and before that AleSmith and Stone Brewing. And he’s published the Complete Guide to San Diego Breweries in 2015. Until recently, I used to run into Brandon fairly regularly at beer functions and he’s become one of my favorite people to hang out with. Join me in wishing Brandon a very happy birthday.

Historic Beer Birthday: Anders Jöns Ångström

August 13, 2025 By Jay Brooks

dark-side-of-moon
Today is the birthday of Anders Jöns Ångström (August 13, 1814–June 21, 1874). He “was a Swedish physicist and one of the founders of the science of spectroscopy.” The Ångström unit (1 Å = 10−10 m) in which the wavelengths of light and interatomic spacings in condensed matter are sometimes measured are named after him. Various types of spectroscopy are employed in the brewing industry.

Anders-Angstrom

Here’s a partial biography of Ångström from Wikipedia:

Anders Jonas Ångström was born in Medelpad to Johan Ångström, and schooled in Härnösand. He moved to Uppsala in 1833 and was educated at Uppsala University, where in 1839 he became docent in physics. In 1842 he went to the Stockholm Observatory to gain experience in practical astronomical work, and the following year he was appointed keeper of the Uppsala Astronomical Observatory.

Intrigued by terrestrial magnetism he recorded observations of fluctuations in magnetic intensity in various parts of Sweden, and was charged by the Stockholm Academy of Sciences with the task, not completed until shortly before his death, of working out the magnetic data obtained by HSwMS Eugenie on her voyage around the world in 1851 to 1853.

In 1858, he succeeded Adolph Ferdinand Svanberg in the chair of physics at Uppsala. His most important work was concerned with heat conduction and spectroscopy. In his optical researches, Optiska Undersökningar, presented to the Royal Swedish Academy of Sciences in 1853, he not only pointed out that the electric spark yields two superposed spectra, one from the metal of the electrode and the other from the gas in which it passes, but deduced from Leonhard Euler’s theory of resonance that an incandescent gas emits luminous rays of the same refrangibility as those it can absorb. This statement, as Sir Edward Sabine remarked when awarding him the Rumford medal of the Royal Society in 1872, contains a fundamental principle of spectrum analysis, and though overlooked for a number of years it entitles him to rank as one of the founders of spectroscopy.

Anders_Ångström_painting

This is the general definition of spectroscopy from Wikipedia:

Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Later the concept was expanded greatly to include any interaction with radiative energy as a function of its wavelength or frequency. Spectroscopic data are often represented by an emission spectrum, a plot of the response of interest as a function of wavelength or frequency.

This abstract from the 2006 paper “Applications of Vibrational Spectroscopy in Brewing” gives an overview of their use by brewers.

The purpose of this chapter is to compile the literature concerning the applications of near‐infrared (NIR), mid‐infrared and Raman spectroscopy in the brewing industry. All these three techniques share the advantages that they are rapid, can be noninvasive and allow direct observation of specific molecular species. As for barley, many researchers have used the NIR reflectance on whole grains in malt evaluation. The NIR determination of α/β‐acids and hop storage index in baled hop samples is reported. NIR spectrophotometric methods have been developed for the determination of yeast concentration and activity in beer making. In addition to the applications in the laboratory of quality control, the overview concerns also the applications of infrared and Raman spectroscopy in monitoring of operation and process control at the essential steps of mashing and wort fermentation in brewery. The results obtained with a short wave NIR spectrophotometer are presented in comparison with long wave NIR spectrophotometers.

Brewers use spectrometers to measure a number of QC items throughout the brewing process.

To get a sense of how much spectrometers are used, this article promoting StellarNet, a company selling them, entitled Spectroscopy Prospects Brewing, is pretty thorough.
