Many people of many nationalities worked on the helicopter as it was developed. The first working helicopter was probably the German Focke-Wulf Fw-61, which first flew in 1936.But the man who made the most important design change was Igor Sikorsky, a Russian who emigrated to the US. He built a helicopter in the US that reached full-scale production in 1942 (131 aircraft built). His design of one main rotor and a small tail rotor became the standard.
The name for the large Marine transport helicopter (CH-47) is Chinook, the name of a Native American tribe. The use of such names is common for US military helicopters (e.g. Apache, Blackhawk).
Dwight Eisenhower was the first to have a presidential heliocopter, starting in 1957.
