Levi Strauss & Co. is an American clothing company known worldwide for its Levi's brand of denim jeans. German immigrant Levi Strauss started his trading business at the 90 Sacramento Street address in San Francisco and then moved the location to 62 Sacramento Street. In 1858, the company was listed as Strauss, Levi (David Stern & Levis Strauss) importers clothing, etc. 63 & 65 Sacramento Street. Jacob Davis, a Latvian immigrant, was a tailor who frequently purchased bolts of denim cloth from Levi Strauss & Co.'s wholesale house. After one of Davis's customers kept purchasing cloth to reinforce torn pants, he had an idea to use copper rivets to reinforce the points of strain, such as on the pocket corners and at the base of the button fly. Davis did not have the money needed to purchase a patent, so he wrote to Strauss suggesting that they go into business together. After Strauss accepted Davis's offer, on May 20, 1873, the two men patented the rivet. The patented rivet was later incorporated into the company's jean design and advertisements. Contrary to an advertising campaign suggesting that Levi Strauss sold his first jeans to gold miners during the California Gold Rush (which peaked in 1849), the manufacturing of denim overalls only began in the 1870s. The company created its first pair of Levi's 501 Jeans in the 1890s. Levi's has been worn by people of all background from miners to actors including Nobel Prize recipients. Marlon Brando and Albert Einstein wore Levi's, and Einstein's leather jacket was made by Levi Strauss & Co. in the 1930s and sold at auction house Christie's in July 2016 for £110,500. As of 2019, the vast majority of Levi's are made overseas in a number of developing countries, such as India, Sri Lanka, Vietnam, and Indonesia.
