     One of the greatest stories of rags to riches success is that of Andrew Carnegie, who started life in

poverty but became one of the richest men in the world.

     Carnegie was born in Scotland in 1835, the son of a weaver. In 1848, the family moved to the United States and at 13 Carnegie began to work in a cotton mill, earning $1.5 per week.About three years later,

he found a better job as a telegraph messenger boy. At work, his superiors (上级) were impressed by

his abilities and willingness to work hard. In 1853, he gained an office job at the Pennsylvania Railroad

Company. This was his first big break. He continued to impress and rose rapidly through the company,

gaining_more_and_more_responsibility.At the same time, Carnegie loved reading very much and made

use of every opportunity to visit the library.He read widely on all subjects, particularly literature.

     Carnegie now began to save a little money and, with the help of his employer, began to make some

successful investments. He invested in the iron industry and eventually set up in business himself, owning

several iron and steel plants. This was where he made his fortune.By the 1890s, the Carnegie Steel

Company was the biggest and most profitable business in the world.

     Carnegie had always believed that the pursuit (追求) of wealth was never an end in itself. In his view,

successful, wealthy people should redistribute their wealth for the benefit of everyone in society. True to

his word, in 1901, at the age of 66, he retired from business and devoted the rest of his life to charity

work.

     Carnegie's lack of formal education and his poor family background clearly didn't put barriers in the

way of success. His rapid rise from poverty to wealth was due to his willingness to work hard, his

intelligence and good business sense, and his talent for making things happen. He died in 1919 at the age

of 83.
