Roald Dahl (norwegian? or english of norwegian parenbtage?) novelist.
Some things to mention:
how he fell into writing by accident: his plane crashed, he was asked for rough notes so it could be turned into a (magazine?) article by a staff writer, and the editor told him he would use the story exactly as written
his appeal to children: rhymes & songs; his tendency to have repulsive characters & ideas (Augustus Gloop, for ex.)
His (great?)-grand-daughter Sophie Dahl is a famous model
his short stories for adults were the basis for the TV series tales of the unexpected.
