Levi Strauss was born in 1829 in Germany and immigrated to the United States where he started a dry goods business with his brothers. In the 1850s, he moved to San Francisco during the Gold Rush and created durable work pants made of denim, known as blue jeans or "Levis." His company Levi Strauss & Co became very successful, and he donated much of his wealth to charities. He passed away in 1902 leaving behind a $6 million estate.
