     Do you enjoy wearing Levi's blue jeans? Blue jeans have become popular all over the world, but

do you know how they got started?

     Levi Strauss was born in Germany in the mid-1800's and immigrated (移居) to the Unit ed States

as a  young man.  He lived in New York City and learned the drygoods business for several years.

In 1853 he took his knowledge and his dreams to San Francisco (California, USA). His dream to

succeed came true over the next 20 years as he became a very successful businessman.

     Many of Levi Strauss' customers were cowboys and miners. They needed clothing that was strong

and lasting. Strauss found a special cloth from France that was comfortable and lasted a long time. It

was called "serge and mines" which was later shortened to the word "denim (粗棉布)".

     Another man named Jacob Davis bought large amounts of the denim cloth from Levi Strauss.

He was a tailor who made pants for hard-working men. One of his customers was continually tearing

the pockets off his pants. So Jacob Davis decided to put rivets (铆钉) on certain parts of the pants

to make them stronger.  The customer loved the new pants so much that he told all his friends, and soon.

Jacob Davis was busy making lots of pants with rivets.

     Jacob Davis soon realized that using rivets was a great business idea, and he didn't want anybody

to steal that idea.  He'decided that he would need to get a patent.  But being a poor tailor, he didn't

have  money to pay for the patent. After thinking it over, he went to the businessman Levi Strauss and

told him   his idea.  He said, "If you agree to pay for the patent, we will share the profits from the riveted

pants.  " Levi Strauss did agree, and the new riveted pant business was called Levi Strauss and Company.

Today  Levi's jeans are more popular than ever, and Levi's name continues to live in.
