Levi's sister Fanny and her husband
David Stern moved to
St. Louis, Missouri, while Levi went to live in
Louisville, Kentucky, and sold his brothers' supplies there. Levi became an
American citizen in January 1853. The family decided to open a West Coast branch of their dry goods business in
San Francisco, which was the commercial hub of the
California gold rush. Levi was chosen to represent them, and he took steamships for San Francisco via Panama, Strauss opened his wholesale business as
Levi Strauss & Co. and imported fine dry goods from his brothers in New York, including clothing, bedding, combs, purses, and handkerchiefs. Tailor
Jacob W. Davis of
Reno, Nevada, was one of his customers; in 1871, having invented a way to strengthen work pants using rivets, he went into business with Strauss to mass-produce them. The next year, Davis asked Strauss to help him apply for a patent, and the patent (one-half assigned to Levi Strauss & Co.) was issued in 1873. ==Death==
