"The Montgolfier brothers, born in Annonay, France, were inventors of the first practical balloon. Joseph-Michael, the elder, was born on August 26, 1740; Jacques-Ètienne was born on January 6, 1745. They were 2 of the 16 children of Pierre Montgolfier, whose prosperous paper factories in the small town of Vidalon, near Annonay, in southern France, helped support their balloon experiments."
