Today is the birthday of Conrad Pfeiffer (March 7, 1854-April 24, 1911). He was born in Germany, possibly Wurzburger, but moved to Detroit, Michigan in 1871, founding the Conrad Pfeiffer Brewery in 1889. In 1902, it became known as the Pfeiffer Brewing Co. which remained its name even after prohibition. With falling sales, in 1962 they changed the name to a more generic Associated Brewing Co., but that only lasted four years with the brewery closing for good in 1966.
And this is the history of the brewery, excerpted from “Detroit Beer: A History of Brewing in the Motor City,” by Stephen C. Johnson:
