1873
The Blue Jean is Born
Jacob Davis, a tailor from Reno, Nevada, teams with Levi Strauss to create riveted-for-strength workwear made of true blue denim. On May 20, 1873 the U.S. Patent and Trademark Office grants patent #139,121 to Levi Strauss & Co. and Jacob Davis for their invention. This is how the blue jean, originally called “XX,” was born.
