Levi Strauss & Co. is a privately held American clothing company known worldwide for its Levi's brand of denim jeans. It was founded in 1853 when Levi Strauss came from Buttenheim, Bavaria, to San Francisco, California to open a west coast branch of his brothers' New York dry goods business. In 1873 Levi Strauss and tailor Jacob Davis received a U.S. patent to make the first riveted men's work pants out of denim: the first blue jeans. The company briefly experimented with a public stock listing, but remains owned and controlled by descendants and relatives of Levi Strauss's four nephews. The company has its corporate headquarters at Levi's Plaza in San Francisco.
