     Booker T. Washington was born in a black slave family in Virginia of the USA in 1856, seven years

before slavery was abolished (废除) by Abraham Lincoln in January, 1863.

     He wrote a book about his life called Up From Slavery, which was published in 1901. In the book,

he said that he had no choice but to work in a coal mine when he was 16 years old. He had no chance to

go to school. He heard two coal miners talking about a school for black children which was called the

Hampton Institute.

     He determined that he would go there. He gave up his job and told other members of his race that he

was going to school across the state. The older people had spent their best years as slaves and were poor. However, some gave Booker some pocket money or a handkerchief. Hardly had anyone expected any

of their race to leave home to attend a boarding school. He took a train to Richmond, Virginia, where he

ran out of money. It was 82 miles from the Hampton Institute. He slept under a wooden sidewalk(人行道).            

     He helped unload pigs and iron from a ship for some money and when he had enough, he continued

his journey, arriving at school with 50 cents.

     This diligence(勤奋) pushed him to graduate and become a teacher at the Hampton Institute. When

he was 25 years old, he was asked to start a new school for black children in Alabama. called the

Tuskegee Normal and Industrial Institute. Thirty-four years later, this school had 1,500 students and 200

teachers and Booker T. Washington became the most influential black leader of his generation.
