Joseph-Michel Montgolfier (26 August 1740 – 26 June 1810) and Jacques-Étienne Montgolfier (6 January 1745 – 2 August 1799) are the inventors of the montgolfière-style hot air balloon, globe aérostatique.

The brothers succeed in launching the first manned ascent, carrying Étienne into the sky.

Later, in December 1783, in recognition of their achievement, their father Pierre is elevated to the nobility and the hereditary appellation of de Montgolfier by King Louis XVI of France.
