Dahl attended School in England but he didn't enjoy the school because many of the teachers were cruel. One of his main hobbies was reading, and some of his favourite novelists were the adventure writers Rudyard Kipling and H. Rider Haggard.
When Dahl was thirteen his family moved to Kent in England, and he was sent to Repton Public School. Sadly, Repton was even harsher than his old school. The headmaster enjoyed beating children and the older students used the younger ones as servants. However, there was one good thing about the school. Every few months, the chocolate company, Cadburys, sent boxes of chocolates to Repton for the students to test. This happy memory gave Dahl the idea for his most famous novel, Charlie and the Chocolate Factory.
In 1939, World War II started, Dahl joined the RAF (Royal Air Force) and learned to fly warplanes. Unfortunately, on his first flight into enemy territory he ran out of fuel and crashed in the Libyan desert. He fractured his skull. He almost died in the burning plane.
Dahl started writing in the 1940s. In 1945 he moved to America, where he met his first wife, the actress Patricia Neal. They had five children together but got divorced in 1983. Dahl remarried soon after. The last years of his life were very happy and he wrote some of his best books during this period: The BFG, The Witches and Matilda. Roald Dahl died on 23rd November 1990 in Oxford, England.
