author
b. 1887
A prolific late-19th- and early-20th-century writer on alcohol policy and brewing, this author explored everything from colonial liquor laws to the history and manufacture of American beer. His books offer a revealing window into the debates around temperance, public policy, and the brewing trade in the United States.

by G. (Gallus) Thomann
Gallus Thomann, often listed as G. (Gallus) Thomann, wrote extensively about liquor laws, temperance debates, and the brewing industry in the United States. Records for works such as Liquor Laws of the United States; Their Spirit and Effect, Colonial Liquor Laws, and The Second International Temperance Congress, Held at Zürich, Switzerland, 1887 show him publishing on these subjects in the late 1880s.
He appears closely connected with the United States Brewers' Association, which published several of his books, including American Beer: Glimpses of Its History and Description of Its Manufacture in 1909 and the multi-volume Documentary History of the United States Brewers' Association. Taken together, these works suggest a writer deeply engaged with both the legal history of alcohol regulation and the public defense of brewing as an industry.
Biographical details about Thomann himself are scarce in the sources I could confirm, so it is safest to remember him through his work: a detailed, often policy-focused body of writing that captures a major American argument over drink, reform, and commerce.
