Gustave Ponton d’Amécourt was a French numismatist (it’s a person who studies currencies and medals) and an archeologist. He was born in 1825 in Paris and he died in 1888. He was the president and the founder of the French society of numismatics. He mainly studied Merovingian Currency. He got the medal of the legion of honor, given by the French president.
He was the inventor of the helicopter. It’s also him who had invented this word. (The word “helicopter” appeared for the first time in 1861).
This inventor built with Gabriel de La Landelle a small prototype of steam power-driven helicopter. The “expensive helix” created by him contributes to solve the problems of air navigation .
My personal opinion :
I think this invention was very useful to progress in diverse fields.
For example, to help people, the helicopter was very useful : for rescuers, it’s a revolutionary means of transportation. They can save people more quickly and in better conditions.
It’s also very useful for the army ans the navigation air.
It’s one of the biggest inventions in History
