Lewis Gerstle
American merchant and philanthropist of Bavarian origin, co-founder of the Alaska Commercial Company. Born Löb Gerstle in 1824 at Ichenhausen, Bavaria, where his family had been established since at least 1538, he emigrated to the United States in the 1840s — accounts differ on the exact year — spent some years in Kentucky, then moved to California. After a brief attempt in gold mining, he partnered with Louis Sloss, another Bavarian, in a wholesale business in Sacramento; the two partners married two sisters, Hannah and Sarah Greenebaum, then settled around 1860 in San Francisco, where they engaged in brokerage, fur trading, tanning, and maritime transport. In 1868, following the U.S. purchase of Alaska, they founded with others the Alaska Commercial Company, which obtained a concession on fur seals, established trading posts, and supplied gold miners during the Klondike Gold Rush in 1897. Administrator of Congregation Emanu-El and the Pacific Hebrew Orphan Asylum, treasurer of the University of California, he died in 1902. His son William Lewis Gerstle (1868–1947), patron and president of the San Francisco Art Association, should not be confused with him.
