Transcript of MONTGOLFIER BROTHERS
Throughout the years people have made these brothers invention bigger and better for everyone to enjoy.
Joseph Michel Montgolfier was born in Annonay, France August 26, 1740
Jacques Etienne Montgolfier was born in Annonay, France January 6, 1745
Joseph observed that laundry drying over a fire formed pockets that billowed upwards.
A BOX LIKE CHAMBER
As a result of these musings, Joseph set about building a box like chamber out of thin wood and covering the sides and top with light weight taffeta cloth.
When the brothers came together they talked about what they had seen. They made blueprints for the balloon .
Then they compromised
with a name which was "HOT AIR BALLOON".
On June 4, 1783 the brothers first demonstrated the flight of a hot air balloon in Annonay, France. A citizen and an army officer volunteered to go in the balloon while flying. Louis XVI, Marie Antoinette and the french court were also there for the flight.
Joseph died on June 26, 1810
Jacques died on August 2, 1799
Greatness and Decay
After the achievement of this flight, hot-air ballooning rapidly became fashionable. The Montgolfier brothers were ennobled by Louis XVI.
The French population was enthusiastic about it but some people soon started to see ballooning as a source of new dangers: borders would disappear, particularly for thieves, private life could be violated and the military forces would use the balloon for reaching bad ends.
The Montgolfier brothers continued with their experiments. They were honored by the French Académie des Sciences. During their careers, they published books on aeronautics, Joseph invented a calorimeter and the hydraulic ram, and Jacques developed a process for manufacturing vellum.
