Founded In 1853, Levi Strauss opened a wholesale dry goods business in San Francisco that became known as Levi Strauss & Co. Seeing a need for work pants that could hold up under rougher conditions, he and Jacob Davis, a tailor, created the first jean. In 1873, they received a U.S. patent for “waist overalls” with metal rivets at points of strain. The first product line designated by the lot number “501” was created in 1890.
