among Americans but also among people around the world.

     Levi Strauss was born in Germany in 1829. 2_____ He grew up in Kentucky before moving to New

York in 1847. Before becoming an American citizen and moving to the West in 1853, Strauss worked in his

brother's dry goods business. This gave him a chance to produce his famous invention. After the gold rush

of 1949, Strauss decided to move to the West to seek his fortunes.

     Strauss did not want to be a person who searched an area for minerals. Instead, he knew he could make

a good living by selling supplies to the miners. At first, he planned to sell sewing supplies and cloth. 3_____

during mining, he decided to use a special fabric to make pants for the miners. These pants proved so popular

that he quickly ran out of materials to make more.

     In 1873, Strauss received a letter from a Jewish tailor named Jacob Davis who had invented a process of
