The Worst Witch

The author Jill Murphy began writing The Worst Witch at the age of 15, while still at school, and based many points of the stories on her own school experiences at Ursuline Convent in Wimbledon, England, with Singing becoming Chanting, Chemistry becoming Potions and so on.

Recalling how the story was initially inspired by her own school experiences, she said in an interview: "My two friends and I used to come home in our dark uniforms, looking very scruffy at the end of the day – my dark plaits sprouting tufts, with lost hair ribbons.

All the characters are based on my school friends (and enemies) and teachers".

Murphy completed the first book at the age of 18, but it was rejected by many publishers (on the grounds that children would find a book about a school for witches too "scary"), so she "put it in a drawer" and concentrated on other things, including working as a nanny and in a children's home, and for a time living in West Africa, where her first husband was studying.

The Worst Witch was finally published in 1974, when Murphy was 24, by the small independent company Allison and Busby.
