One of the most popular articles of clothing in America, blue jeans, were patented on May 20, 1873 by Levi Strauss and Jacob Davis.
Levi Strauss, a 24-year-old German immigrant in San Francisco, began making overalls out of a type of cotton fabric from France called “serge de Nimes” and selling them to miners. This cloth would later come to be known as denim and nicknamed “blue jeans”.
Levi Strauss & Company began using a pocket-stitch design to make the pants and employed the help of Nevada tailor Jacob Davis to help invent the method of sewing rivets into the pants for added durability. The two received U.S. Patent 139,121 on May 20, 1973 which is considered the birthday of blue jeans.
