Parachutes. The parachute was invented by Andre AndrÃ© Jacques (garnerin-1769). 1823 it consisted of a white canvas canopy 23 feet in. Diameter the parachute had 36 ribs and, lines was-semi, rigid making it look like a very large. Umbrella garnerin made his first successful parachute jump Above paris on 22nd, october. 1797s Garnerin failed to include an air vent at the top of his parachute, he oscillated wildly in his descent. However, he landed unhurt half a mile from the balloon's takeoff site. Garnerin therefore became the first man to design a parachute that was capable of slowing a man's fall from a high altitude.
In 1919 Leslie Irvin invented and successfully tested a parachute that the pilot could deploy when clear of the aircraft. An early brochure [1] of the Irvin Air Chute Company credits William O'Connor 24 August 1920 at McCook Field near Dayton, Ohio as the first person to be saved by an Irvin parachute.
