Igor Sikorsky is the first who invented the helicopter in 1940. But Leonardo da Vinci was the first who had an idea of a helicopter.!

Toys based on the principle of the rotary wing of the helicopter were prevalent in China as early as 400 BC. These toys made it to Europe and in 1490 Leonardo da Vinci designed a Helicopter that could lift a man. The design was theoretically probable but like most of his other inventions practically preposterous.

In 1907 Paul Cornu a French inventor managed to make his twin rotor helicopter lift into the air for a very short interval of time.

The initial problems that helicopters faced were the lack of a powerful engine and of torque. The internal combustion engine and the tail rotor successfully solved this problem.

Even though many inventors worked and developed helicopters over the years the first successful helicopter was built by Frenchmen Louis Breguet and Rene Dorand in 1935. Their machine based on a coaxial design flew for 62 minutes and covered a distance of 44 km.

Leonardo da Vinci is made the first detailed drawings. But he didn't really understand the physics of how it would work. Long before da Vinci, the Chinese had come up with a child's toy that could hover briefly (using the energy from winding something up or an elastic band).

Inventors in following centuries kept tinkering with the idea, but they didn't have a strong enough engine to create the necessary power (and they didn't really understand how lift would work, either).

The internal combustion engine changed all that. Suddenly the had enough power... but they also had a lot of unforeeseen problems. Chief among these was torque, the tendency of the blades to push the helicopter fusealoge around in circles. In 1907 a French engineer, Paul Comu, managed to lift a twin-rotor model off the ground for a few seconds, but this was slow progress. In 1924 another Frenchman, Etienne Oehmichen demonstrated a helicopter that flew for over 7 minutes on a 1km course. It still wasn't until the late 1930s that helicopters became reliable machines of flight.
