Judith Kerr was a German-born British writer and illustrator whose books have sold more than 10 million copies worldwide. She is known for creating enduring picture books such as the Mog series and The Tiger Who Came to Tea, as well as acclaimed novels for older children like the semi-autobiographical When Hitler Stole Pink Rabbit, which provides a child's-eye view of escaping Hitler's persecution during the Second World War.

Kerr was born in the Weimar Republic and fled to Britain with her family in 1935 to escape the rise of the Nazis, as her father, noted drama critic, journalist, and screenwriter Alfred Kerr, had openly criticized the Nazis. The family first sought refuge in Switzerland and France before finally settling in Britain.
