     Robert Frost was one of America's best known and most honored serious writers. But his fame came

late in his life.

     He was born in San Francisco, California in 1874. He lived in California during his early childhood. He was named after the chief Southern general in America's Civil War. The general's name was Robert

Edward Lee. The poet was named Robert Lee Frost, because his father wanted to honor the general.

     Someone once asked another American writer, Ernest Hemingway, how to become a writer. The best 

thing, he said, was to have an unhappy childhood. If this is true, Robert Frost's childhood was unhappy

enough to make him a very good writer. Robert Frost's father was a reporter who wanted to be a

politician. He often drank too much wine and became angry. Robert was the victim of his anger.

     Robert Frost finished high school in 1891. After high school, Robert's grandfather offered to pay his

costs at Dartmouth College. But Robert left the school after a few months. He did not like it. He spent the next few years working at different jobs. At one time, he worked in a factory. Later, he repaired shoes. He was a teacher. He was a reporter. Always, he wrote poetry.

     Robert Frost attended Harvard University for two years. After that, he returned to the many jobs he

held before. For a while, Frost tried to take care of a farm in the state of New Hampshire. He was not a

successful farmer. And he continued to write poetry. He said that until 1930, he earned only about ten

dollars a year from writing.

     In 1912, he decided to try to make a new start. He took his family to Britain. The cost of living was low. In Britain, Frost found a publisher for his first book of poems. The book was called A Boy's Will.

When it appeared in 1913, Frost received high praise from British readers. Praise was something he had

not received in his own country.

    Ezra Pound, another American poet living in Britain, read the poems and liked them very much. He

wrote a magazine article about Frost. He also helped get Frost's second book of poems published in

America. That book was called North of Boston.
