Riveted Jeans

In the 1850s Levi Strauss, a German dry goods merchant living in San Francisco, was selling blue jeans under the "Levi's" name to the mining communities of California. One of Strauss's customers was Jacob Davis, a tailor who frequently purchased bolts of cloth from the Levi Strauss & Co 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 required money to purchase a patent, so he wrote to Strauss suggesting that they both go into business together. After Strauss accepted Davis's offer, on May 20, 1873, the two men received patent #139,121, a patent for an "Improvement in Fastening Pocket-Openings," from the United States Patent and Trademark Office.
