Levi Strauss (February 26, 1829 – September 26, 1902) was a German-Jewish immigrant to the United States who founded the first company to manufacture blue jeans. His firm, Levi Strauss & Co., began in 1853 in San Francisco, California. In late 1870 Jacob Davis, a Reno, Nevada tailor, started making men’s work pants with metal rivets at points of strain for greater strength. He wanted to patent the process but needed a business partner, so he turned to Levi Strauss, from whom he purchased some of his fabric. On May 20, 1873, Strauss and Davis received United States patent #139121 for using copper rivets to strengthen the pockets of denim work pants. Levi Strauss & Co. began manufacturing the famous Levi’s brand of jeans, using fabric from the Amoskeag Manufacturing Company in Manchester, New Hampshire.
