in 1907 the first manned helicopter, designed by louis breguet, hovered for one minute above the ground. some five hundred years earlier leonardo da vinci sketched such a craft.
He did not, Leonardo da Vinci did.
No single person invented it. Like many things it evolved through the experimentation and adaptation of many brilliant men and women. The key issue here is considering a machine that could make sustained and controllable flights. There have been machines of various sizes and shapes that might have been able to lift into the sky, but designing one that could stay there for any length of time, or that could be controlled in all axes is the yardstick to be used to measure accomplishment. Igor Sikorsky is credited as building the first practical helicopter in the US (and the world's first mass-produced helicopter, the R-4, since the German machines built during WWII really weren't mass-produced), however the Germans had a flyable one several years before Sikorsky did (look up Prof. Focke and the Fw-61). And going back even further Juan Cierva of Spain can be credited with what is probably the most important invention in helicopter design when he developed an articulated rotor system for his autogyro (gyroplane).
It is a matter of definition. Some authorities label the Flemish 1400s as 'Late Gothic'. 'I would not mind calling this Renaissance art.
He sketched the first parachute, first helicopter, first aeroplane, first tank, first repeating rifle, swinging bridge, paddle boat and first motor car. Da Vinci designed machines of war as well. He was one of the first artists to sketch outdoor portraits. Da Vinci was a sculptor and designer of costumes. He was also a mathematician and a botanist.
