the Montgolfier brothers were 2 french brothers called "Etienne and Michel Montgolfier" later in their life they tried very hard to create the "hot air balloon"! It took so many tries they almost gave up but eventually they made it and after experimenting for a year and a half they had invented the hot air balloon! (Probably not true!)
