Denim Blue JeansLevi Strauss had the canvas made into waist overalls. Miners liked the pants, but complained that they tended to chafe. Levi Strauss substituted a twilled cotton cloth from France called "serge de Nimes." The fabric later became known as denim and the pants were nicknamed blue jeans.
Levi Strauss & CompanyIn 1873, Levi Strauss & Company began using the pocket stitch design. Levi Strauss and a Reno Nevada-based Latvian tailor by the name of Jacob Davis co-patented the process of putting rivets in pants for strength. On May 20, 1873, they received U.S.Patent No.139,121. This date is now considered the official birthday of "blue jeans."
Levi Strauss asked Jacob Davis to come to San Francisco to oversee the first manufacturing facility for "waist overalls," as the original jeans were known as.
The two-horse brand design was first used in 1886. The red tab attached to the left rear pocket was created in 1936 as a means of identifying Levi’s jeans at a distance. All are registered trademarks that are still in use.
