The modern parachute was invented in the 18th century by Louis-S矇bastien Lenormand in France, who made the first recorded public jump in 1783. In 1785, Jean-Pierre Blanchard demonstrated it as a means of safely disembarking from a hot-air balloon. While Blanchard's first parachute demonstrations were conducted with a dog as the passenger, he later claimed to have had the opportunity to try it himself in 1793 when his hot air balloon ruptured and he used a parachute to descend (this event was not witnessed by others). Subsequent development of the parachute focused on it becoming more compact. While the early parachutes were made of linen stretched over a wooden frame, in the late 1790s, Blanchard began making parachutes from folded silk, taking advantage of silk's strength and light weight. In 1797, Andr矇 Garnerin made the first descent using such a parachute. He also invented the vented parachute, which improved the stability of the fall.
