William Grattan Tyrone Power (1795 – 17 March 1841), known professionally as Tyrone Power, was an Irish stage actor, comedian, author and theatrical manager.
Born in Kilmacthomas, County Waterford, to a landed family, the son of Maria Maxwell and Tyrone Power, he took to the stage achieving prominence throughout the world as an actor and manager. He is said to have purchased the land that would later be occupied by Madison Square Garden, New York shortly before his death at sea when his ship, the SS President, sank shortly after departing for England. The lawyer who held the papers could not be found so the Power family were unable to claim right to the property.
He was well known for acting in such Irish-themed plays as Catherine Gore’s King O’Neil (1835), his own St. Patrick’s Eve (1837), Samuel Lover’s Rory O’More (1837) and The White Horse of the Peppers (1838), Anna Marie Hall’s The Groves of Blarney (1838), Eugene Macarthy’s Charles O’Malley (1838), and Bayle Bernard’s His Last Legs (1839) and The Irish Attorney (1840).
