Canvas, Silk and Nylon. The canopy of the parachute was initially made of canvas, which was eventually replaced by silk, which was thinner, lighter, stronger, fire resistant and easy-to-fold. In late 1930s and early 1940s, the World War affected silk import in the United States.
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, Andrew Garnerin made the first jump using such a parachute. Garnerin also invented the vented parachute, which improved the stability of the fall. In 1890, Paul Letteman and Kathchen Paulus made the first knapsack parachute. On March 1, 1912, US Army Captain Albert Berry made the first parachute jump from a moving airplane over Missouri. Å tefan BaniÄ from Slovakia registered the first modern parachute patent in 1913.
