H. Truesdell Smith—known variously as "H. T. Smith", "Henry Truesdell Smith", "Harold Truesdell Smith", or "Daredevil Smitty" but best known as "Smitty the Jumper"—was an American exhibition parachutist and skydiver of the 1920s and 1930s. He made periodic returns to skydiving starting in the late 1950s, jumping in every subsequent decade until his death, becoming widely known as "the oldest living skydiver", a title he claimed until his death in 1995 at the age of 96.
