Levi Strauss & Co. is noted especially for its blue denim jeans called Levi’s. The company traces its origin to Levi Strauss (1829–1902), a Bavarian immigrant who arrived in San Francisco in 1850 during the Gold Rush, bringing dry goods for sale to miners. Hearing of the miners’ need for durable pants, Strauss hired a tailor to make garments out of tent canvas. Later, denim was substituted, and copper riveting was added to pocket seams. A merchandising partnership of Strauss and his two brothers, Jonas and Louis, was formed in 1853.
