French designers of the hot-air balloon.

The brothers discovered that heated air collected in a lightweight bag would cause the bag to rise. In 1783 they demonstrated their discovery with a balloon that rose 3,000 ft (1,000 m) and remained aloft 10 minutes. Later that year they sent a sheep, a duck, and a rooster up as passengers, and they followed that experiment with the first manned untethered balloon flight.
