Henry Every, also known as Henry Avery (born 20 August 1659; disappeared June 1696), sometimes erroneously given as Jack Avery or John Avery, was an English pirate who operated in the Atlantic and Indian oceans in the mid-1690s. He probably used several aliases throughout his career, including Benjamin Bridgeman, and was known as Long Ben to his crewmen and associates. Dubbed the Arch Pirate and the King of Pirates by contemporaries, Every was infamous for being one of the very few major pirate captains to escape with his loot without being arrested or killed in battle, and for being the perpetrator of what has been called the most profitable act of piracy in history.
