Étienne de Montgolfier (Joseph's son)

Étienne de Montgolfier, the son of Joseph Montgolfier, was a French inventor and engineer in the 18th century. He, along with his father, played a key role in developing the first hot air balloons, known as "montgolfières," which used heated air to lift and fly. Their pioneering experiments in ballooning helped establish lighter-than-air flight, marking the beginning of human aviation. Étienne’s contributions complemented his father’s work, and together they advanced scientific understanding of aeronautics, inspiring future innovations in air travel.
