Forty breweries existed in St. Louis when Eberhardt Anheuser bought, before the Civil War, the Bavarian Brewery. His daughter, Lilly, married Adolphus Busch who sold supplies to the brewery. After the Civil War, Busch joined his father-in-law in the brewing business. Carl Conrad, a native of Budweis, Bavaria, was Busch’s good friend who developed a formula for a new, light lager beer. Recently merged, AB-InBev is today the world’s largest brewery.
