Jack Sheppard (4 March 1702 – 16 November 1724) was a notorious English thief and gaol-breaker of early 18th-century London. Born into a poor family, he was apprenticed as a carpenter but took to theft and burglary in 1723, with little more than a year of his training to complete. He was arrested and imprisoned five times in 1724 but escaped four times from prison, making him a notorious public figure, and wildly popular with the poorer classes.
