OUR STORY
THE HISTORY OF DENIM
May 20, 1873 marked an historic day: the birth of the blue jean. It was on that day that Levi Strauss and Jacob Davis obtained a U.S. patent on the process of putting rivets in men’s work pants for the very first time.

Levi Strauss, a Bavarian-born dry goods merchant, came to San Francisco in 1853 at the age of 24 to open a West Coast branch of his brothers’ New York wholesale dry goods business. Over the next 20 years, he built his business into a very successful operation, making a name for himself not only as a well-respected businessman, but also as a local philanthropist. One of Levi’s customers was a tailor named Jacob Davis.
