     Jeffrey Bezos, the founder, president and chairman of the board of Amazon.com, was born in Albuquerque,

New Mexico. His mother's ancestors were early settlers in Texas, and over the generations had acquired a

25,000 acre farm at Coutlla. Jeffrey spent most summers of his youth working with his grandfather on their

farm.

     Jeffrey showed intense and varied scientific interests at an early age. He set up an electric alarm to keep his

younger sisters and brothers out of his room and changed his parents' garage into a laboratory for his science

projects.

     After he graduated from Princeton University with a degree in computer science and electrical engineering,

Jeffrey Bezos found employment on Wall Street, where computer science was increasingly in demand to study

market trends. He rose quickly, becoming a senior vice president, and looked forward to a bright career in

finance, when he made a discovery that changed his life, and the course of business history.

     In 1994, there was still no Internet commerce to speak of. One day that spring, Jeffrey Bezos observed that

Internet usage was increasing by 2,300 percent a year. He saw an opportunity for a new circle of commerce,

and immediately began considering the possibilities.

     Bezos founded Amazon.com in 1994, setting up the original company in his garage. The company was

called Amazon for the seemingly endless South American river with its numberless branches. It started as an

online bookstore but soon diversified (多样化) to all kinds of products. His work with Amazon eventually led

him to become one of the most excellent dot-com entrepreneurs (企业家). He was named Time magazine's

Person of the Year in 1999. In 2008, he was selected by U.S. News & World Report as one of America's Best

Leaders. Bezos' Amazon has become "the Earth's biggest anything store". Amazon.com is now called" one of

the smartest strategies in business history".

     Today, Jeffrey Bezos lives north of Seattle and is increasingly concerned with charity (慈善) activities.

"Giving away money takes as much attention as building a successful company," he has said.
