Some think that a form of a primitive parachute was mentioned by Chinese texts 21 centuries ago. In 9th century Abbas Ibn Firnas and Ali Ben Isa (of Arabic origin) also created one of the earliest versions of a parachute which John H. Lienhard described as "a huge winglike cloak to break his fall" .
A conical parachute appears for the first time in the 1470s in an Italian manuscript, slightly preceding Leonardo da Vinci's conical parachute designs . It was intended as an escape device to allow people to jump from burning buildings, but there is no evidence that it was actually ever used.
Many think that the first modern conical parachute design had been imagined and sketched by Leonardo Da Vinci in the 15th century.
Leonardo's parachute design consists of sealed linen cloth held open by a pyramid of wooden poles, about seven metres long. The original design was scribbled by Da Vinci in a notebook in 1483. An accompanying note read: "If a man is provided with a length of gummed linen cloth with a length of 12 yards on each side and 12 yards high, he can jump from any great height whatsoever without injury."
Maybe the first implemented parachute was created in 1595 by the Croatian inventor Faust Vrančić, who named it Homo Volans (Flying Man). Twenty years later, he implemented his design and tested the parachute by jumping from a tower in Venice in 1617 .
Credit for the invention of the first practical parachute frequently goes to Sebastien Lenormand who demonstrated the parachute principle in 1783.
A French aeronaut (pilot of a balloon or lighter-than-air aircraft), Jean Pierre Blanchard, claimed the invention of the parachute in 1785, and the first successful parachute descent from a great height was made in 1797 by the French aeronaut Jacques Garnerin, who dropped 3,000 ft (920 m) from a balloon. Parachutes began as an escape system for persons aboard balloons or aircraft unable to land safely. In 1887, Captain Thomas Baldwin invented the first parachute harness and in 1890, Paul Letteman and Kathchen Paulus invented the method of folding or packing the parachute in a knapsack to be worn on the back before its release.
On Tuesday, 27 June, 2000 BBC News Online's Dr Damian Carrington reported that Leonardo Da Vinci was proved right, over 500 years after he sketched the design for the first parachute.
A British man, Adrian Nicholas, dropped, with a Da Vinci implemented parachute, from a hot air balloon 3,000 metres (10,000 feet) above the ground, after ignoring expert advice that the canvas and wood contraption would not fly beacuse of weight.
The parachute's great weight was due to the use of materials that would have been available in medieval Milan like canvas and wood.
Mr Nicholas said he thought Da Vinci would have been pleased, even if the vindication of his idea came five centuries late.
