Levi Strauss was a German-American businessman who founded the first company to manufacture blue jeans. His firm, Levi Strauss & Co., began in 1853 in San Francisco, California.
At the age of 18, Strauss, his mother and two sisters traveled to the United States to join his brothers Jonas and Louis, who had begun a wholesale dry goods business in New York City called J. Strauss Brother & Co.
The family decided to open a West Coast branch of the family dry goods business in San Francisco, which was the commercial hub of the California Gold Rush. Levi was chosen to represent the family and he took a steamship for San Francisco, arriving in early March 1853, where he joined his sister's family.
Strauss opened his dry goods wholesale business as Levi Strauss & Co. and imported fine dry goods—clothing, bedding, combs, purses, handkerchiefs—from his brothers in New York. He made tents, and later jeans. Levi lived with Fanny's growing family.
Jacob Davis, one of Strauss's customers and one of the inventors of riveted denim pants in 1871, went into business with Strauss to produce blue jeans. The two men patented the new style of work pants in 1873.
