Ursula K. Le Guin
Le Guin had not planned to write for young adults. But, the editor of Parnassus Press asked her to write a novel for young people. He thought they could sell many books to that group. He published A Wizard of Earthsea in 1968. It was a fantasy coming of age story for teenagers. In the book, Le Guin created a fictional archipelago called Earthsea. She also created the first wizarding school. Readers and reviewers in the US and the UK liked the book very much.
