Levi Strauss
In 1872, Levi received a letter from Jacob Davis, a Reno, Nevada tailor. Davis was one of Levi Strauss' regular customers, who purchased bolts of cloth from the company to use for his own business. In this letter, Davis told Levi about the interesting way in which he made pants for his customers: he placed metal rivets at the points of strain—pocket corners and on the base of the fly. As he did not have the money to patent his process he suggested that Levi pay for the paperwork and that they take out the patent together.
