yes he did invent the jeans
yes Levi Strauss did make jeans

Levi Strauss made his fortune in the California Gold Rush as the maker of sturdy pants -- Levi's, the world's most famous denim jeans. Strauss emigrated to New York from Bavaria in 1847, then made his way to the San Francisco area in 1853. A tailor who had planned to make tents for miners, Strauss ended up stitching canvas pants that became famous for their durability. The "pants of Levi's" came to be called simply Levi's, and they became one of the best-selling products in his dry goods store. He began using fabric from Nîmes, France, serge de Nîmes (the origin of the word denim), then added dye to make them blue. In the 1870s he partnered with Jacob Davis of Nevada to add copper rivets to the pockets. Levi Strauss & Company became one of the world's largest manufacturers of casual clothing and Strauss himself became a wealthy patron of the city of San Francisco. Strauss was a lifelong bachelor, and after his death in 1902 his nephews took over the company.
