Stephen and Joseph Montgolfier were papermakers, but they had been interested in flying for many years. One night, in1782, Joseph noticed something that gave him an idea. He was sitting in front of the fire when he saw some small pieces of scorched paper being carried up the chimney.

Soon afterwards the brothers made an experiment. They lit a fire under a small silk bag, which was open at the bottom. At once the bag rose to the ceiling. After this, Stephen and Joseph made many more experiments, both indoors and out in the open air. Then they built a huge balloon of linen and paper. On June 5th, 1783, they sent this balloon up in the village of Annonay where they lived.
