Origins of the NameIn 1863, the French writer Ponton D'Amecourt was the first person to coin the term "helicopter" from the two words "helico" for spiral and "pter" for wings.
The very first piloted helicopter was invented by Paul Cornu in 1907, however, this design was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924. Another early helicopter that flew for a decent distance was the German Focke-Wulf Fw 61, invented by an unknown inventor.
Igor SikorskyIgor 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 born Igor Sikorsky began work on helicopters as early as 1910. By 1940, Igor Sikorsky's successful VS-300 had become the model for all modern single-rotor helicopters. He also designed and built the first military helicopter, XR-4, which he delivered to Colonel Franklin Gregory of the U.S. Army.
Igor Sikorsky's helicopters had the control to fly safely forwards and backwards, up and down, and sideways. In 1958, Igor Sikorsky's rotorcraft company made the world's first helicopter that had a boat hull and could land and takeoff from water. It could also float on the water.
Stanley HillerIn 1944, American inventor Stanley Hiller, Jr. made the first helicopter with all metal rotorblades that were very stiff. They allowed helicopter to fly at speeds much faster than before. In 1949, Stanley Hiller piloted the first helicopter flight across the United States, flying a helicopter that he invented called the Hiller 360.
In 1946, Arthur Young of the Bell Aircraft company, designed the Bell Model 47 helicopter, the first helicopter to have a full bubble canopy.
