In 1863, the French writer Ponton D'Amecourt was the first person to create the word "helicopter" from the two words "helico" for spiral and "pter" for wings. The very first helicopter was invented by Paul Cornu in 1907, but it was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924.

However, Igor Sikorsky is considered to be the father of helicopters not because he invented the first. He is called that because he invented the first successful helicopter, upon which further designs were based. One of aviation's greatest designers, Russian bom Igor Sikorsky began work on helicopters as early as 1910. By 1940, Igor Sikorsky's successful VS-300 had become the model for all modem helicopters of today. He also designed and built the first military helicopter.
