What are facts about the montgolfier brothers?

The Montgolfier brothers, Joseph-Michel and Jacques-Étienne, were French pioneers of ballooning who invented the hot air balloon in the late 18th century. Their first successful flight took place on June 4, 1783, when they launched a paper balloon that rose about 1,000 meters into the air. They conducted several public demonstrations, including a notable flight with a manned balloon in 1783, which carried a sheep, a duck, and a rooster. Their innovations laid the groundwork for the development of modern aeronautics and sparked widespread interest in human flight.
