I can’t find out much about Adolph Keitel, but in 1918, he wrote “Government by the Brewers?”. It was published in Chicago, and is an anti-brewery/anti-beer tract. It’s available from Project Gutenberg, the free etext archive.
His argument is a bit odd – he’s not anti-prohibition, but he’s annoyed that brewers were trying to convince people beer was less harmful than whisky. He says that beer is a habit forming drug (“It’s not a drug – it’s a drink” – Chris Morris) and not fit to be in the home. Brewers, he argues, are a sinister force for evil.
This point re: the quality of American beer is particularly amusing:
WHAT IS BEER?
In the well known European beer drinking countries nothing but hops and malt are permitted in brewing.
Here beer is a concoction of corn, rice, hops, malt, glucose,preservatives and other drugs–and, in most cases, it has nothing in common with real beer other than its artificial foam and color.
A leader of public opinion made the statement in the United States Senate that “Beer that is brewed in this country is slop. They say it is ‘good for the health.’ I never saw a man who drank it who was not a candidate for Bright’s disease or paralysis.”
