Benjamin Franklin, who was to become one of the best known American writers, politicians and scientists, was born in Boston in 1706. He was one of 17 children, and as a child, he worked in the shop of his father, who was a soap and candle maker. As he loved to read and study, however, working for his father did not appeal to him, so when he was 12, he was sent to assist his brother James, who had a printing shop. There, surrounded by books, he would often stay up late at night reading on a wide range of subjects. As he read, he practised improving his own style of writing.
