November 26, 1783, French chemistry professor Sebastien Lenormand conceives the first parachute.

On this day (November 26), 1783, the French chemistry professor Sebastien Lenormand conceived the first parachute.
Louis-Sébastien Lenormand was born on May 25, 1757 and was a chemist, physicist, inventor and pioneer of skydiving.
A parachute is a device used to slow down the movement of an object through a atmosphere creating drag (or in the case of compressed air parachutes, lift aerodynamics).
In 852, in Córdoba, Spain , the Moor Armen Firman tried unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent a great injury when he hit the ground".
The earliest evidence for a true parachute dates back to the period of the Renaissance . The earliest parachute design appears in an anonymous manuscript from Renaissance Italy of the 1470s (British Library, Add MS 34113, fol. 200v), showing a free-hanging man grasping a crossbar frame attached to a conical canopy.
Shortly thereafter, the scholar Leonardo da Vinci sketched a parachute more sophisticated in its Codex Atlanticus (fol. 381v) dated ca. 1485
In 1785, Lenormand coined the word "parachute" by hybridizing an Italian prefix para , an imperative form of parare = to avoid, defend, resist, guard, shield or cover, from stop = to Parry and ramp , the French word for autumn , to describe the actual function of the aeronautical device.
After jumping out of a tree with the help of a pair of modified umbrellas, Lenormand refined his contraption and on 26 December, Joseph Montgolfier , using a 14-foot parachute with a rigid wooden frame. His intended use for the parachute was to help trapped occupants of a burning building escape unharmed.
As a curiosity to comment that after the public demonstration of the parachute, Lenormand dedicated himself to establishing the science of "technology pure". To this end, he first became a Carthusian monk, since the Saïx monastery near Castres allowed him to continue his "profane" studies.

- Son, what are you doing?
- I'm sewing mommy
- very good
- thank you
- are you sewing a sheet?
- no, it's a parachute
- it looks like a savannah
- looks like but isn't
- and what does a parachute do?
- will help you jump from a great height without hurting yourself
- have you ever tried it?
- no
- well, let your father-in-law try it first
- why?
- because if it doesn't work we won't miss it either
- to the parachute?
- no, your father-in-law
