Jacques-Étienn Montgolfier

Jacques-Étienne Montgolfier was a French inventor born in 1745, best known for developing hot air balloons. Along with his brother, Joseph-Michel, he discovered that heated air causes balloons to rise by experimenting with paper and fabric vessels filled with warm air. Their pioneering flights in the late 18th century marked the first successful human-carrying flight, laying the foundation for modern aeronautics. His work significantly advanced understanding of flight and inspired future technological innovations in aviation.
