Roald was born in Llandaff in Wales on 13 September 1916. His parents were both from Norway but they moved to the UK before he was born. He went to several different boarding schools, living away from his parents for most of the year. Once, to play a trick on the owner of a sweet shop, he put a dead mouse in one of the jars of sweets! As punishment for that, he was caned (hit with a stick) at school. In fact, Roald hated violence and cruel behaviour, and in many of his stories the main characters are treated cruelly by their family, carers or teachers. However, they always come out on top.
