Jacques-Etienne de Montgolfier. Coloured portrait of the French co-inventor of the hot-air balloon Jacques- Etienne de Montgolfier (1745-1799). Along with his brother,Joseph,Jacques pioneered aeronautics in the eighteenth century. In 1782 the brothers discovered that heated air collected inside a lightweight paper or fabric bag caused the bag to rise into the air. The first manned balloon flight took place in Paris,France,in 1783 in a balloon designed by the brothers. The Montgolfier design was incorporated in larger balloons that opened the way to exploration of the upper atmosphere | |
