Beer Magnate. In 1839 he emigrated to the United States, carrying with him the recipe for lager, a popular brew in Germany that was then unknown in America. He joined his brother Frederick in the employ of a local brewer, and in 1842 the Schaefer brothers bought out the owner, establishing F & M Schaefer Brewing. Lager proved popular and the Schaefer company became one of the country’s largest beer producers, with Maximilian Schaefer remaining active in the company until failing health caused him to retire in the late 1890s. By the early 1900s, its customer base in the Northeastern United States made Schaefer the most popular beer in the country, a position it maintained until ceding it to Budweiser in the 1970s. The Schaefer brand continued to decline, and as of 1999 is owned by Pabst Brewing, a holding company that contracts for the brewing of formerly popular regional brands.
