Parachute-by Leonardo Da Vinci. The first parachute (. ) had been imagined and sketched by Leonardo Da Vinci in the 15th century. It's hard to believe something as modern as a parachute could be invented over 500 years ago. Leonardo's parachute design consists of sealed linen cloth held open by a pyramid of wooden poles, about seven metres long.
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.
