The hot-air balloon was devised by Joseph and Jacques Montgolfier, two brothers from France. The Montgolfier brothers worked in their own papa’s paper factory in Annonay, France. While working there, they found how fires sent bits of paper floating up the chimney and became convinced a big bag full of hot air would also rise. Their first balloon was made of cloth lined with paper. It was 10 m (33 feet) across. On 19 September 1783, a sheep, a duck and a cockerel became the first living creatures to fly in free flight when they took off in a wicker basket hung from a Montgolfier balloon.
