Following the Montgolfier brothers' pioneering 1783 balloon flights in Paris, the ballooning craze spread rapidly across France, with the brothers themselves conducting further demonstration flights in their hometown region. These flights helped cement France's status as the birthplace of human flight and inspired a wave of scientific and public fascination with aeronautics across Europe.
The Montgolfier brothers, Joseph and Étienne, were paper manufacturers from Annonay who had discovered that heated air trapped inside a lightweight bag could generate lift. Their first public demonstration in June 1783 sent an unmanned balloon soaring over their hometown; by November they had launched the first manned flight over Paris carrying Jean-François Pilâtre de Rozier and the Marquis d'Arlandes.
As word spread, competing balloonists and the Montgolfiers themselves staged further ascents to satisfy an increasingly balloon-obsessed public, with Lyon becoming a center of aeronautical experimentation given its proximity to the brothers' base. Crowds in provincial cities gathered by the thousands to watch these fragile paper-and-linen vessels rise.
The balloon mania of 1783 triggered immediate scientific rivalry, most notably with Jacques Charles's hydrogen balloon flights, and within a decade balloons were being used for military reconnaissance during the French Revolutionary Wars. The Montgolfiers had, almost by accident, opened the sky to humanity.
