 Jack Sheppard was a notorious English thief of the early 18th century, famous for his four daring escapes from prison. He was popular with the poorer classes for his clever escapes, mockery of the police, non-violent methods and witty, genial attitude. His story inspired many Victorian artists and writers, and was even adapted for the stage.
