Cornelis Jol, Dutch admiral (b. 1597)
Cornelis Corneliszoon Jol (1597 – 31 October 1641), nicknamed Houtebeen ("pegleg"), was a 17th-century Dutch corsair and admiral in the Dutch West India Company during the Eighty Years' War between Spain and the Dutch Republic. He was one of several early buccaneers to attack Campeche, looting the settlement in 1633, and was active against the Spanish in the Spanish Main and throughout the Caribbean during the 1630s and 40s.

Jol was really more of a pirate (or rather privateer) than an admiral, raiding Spanish and Portuguese fleets and gathering large amounts of loot. He was nicknamed Houtebeen (Perna de Pau in Portuguese and Pie de Palo in Spanish), because he lost a leg during battle and became one of the earliest documented pirates to use a wooden peg leg. The Spanish also nicknamed him El Pirata.
