Paul Cornu, of Romanian origins, [1] was born in Glos la Ferrière, France and was one of thirteen children. At a young age, he helped his father in his transports company. [2] He made history by designing the world's first successful manned rotary wing aircraft. Cornu first built an unmanned experimental design powered by a 2 hp Buchet engine. [3]
View from the Window at Le Gras 1826 or 1827, believed to be the earliest surviving camera photograph. [1] Original (left) and colorized reoriented enhancement (right).. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection; the second is the discovery that some substances are visibly altered by exposure to light.

The Cornu helicopter was an experimental helicopter built in France, and is widely credited with the first free flight of a rotary-wing aircraft when it took to the air on 13 November 1907. Built by bicycle -maker Paul Cornu , it was an open-framework structure built around a curved steel tube that carried a rotor at either end, and the engine ...
This helicopter-like top originated in Jin dynasty China around 320 AD, [1] and was the object of early experiments by English engineer George Cayley, the inventor of modern aeronautics. [2] In China, the earliest known flying toys consisted of feathers at the end of a stick, which was rapidly spun between the hands and released into flight.
The first time a manned helicopter is known to have risen off the ground was on a tethered flight in 1907 by the Breguet-Richet Gyroplane. Later the same year the Cornu helicopter, also French, made the first rotary-winged free flight at Lisieux, France. However, these were not practical designs.
Richard William Pearse (3 December 1877 – 29 July 1953) was a New Zealand farmer and inventor who performed pioneering aviation experiments. Witnesses interviewed many years afterwards describe observing Pearse flying and landing a powered heavier-than-air machine on 31 March 1903, nine months before the Wright brothers flew.
The first sustained powered, controlled flight in history is believed to have taken place on 24 September 1852 when Henri Giffard flew about 17 miles (27 km) in France from Paris to Trappes with the Giffard dirigible, [45] a non-rigid airship filled with hydrogen and powered by a 3 horsepower (2.2 kW) steam engine driving a 3-bladed propeller.
The AH-4 helicopter in flight. In 1928, Asboth followed up the earlier experimental work on vertical take-off aircraft, carried out during World War I by Petróczy, Kármán and Zurovec. The original prototypes carried a car for an observer and allowed rapid vertical flight using tethering cables to hold them in position and aid stability. [1]
