WITH: BOURGEOIS, David: Recherches sur l'Art de voler, depuis la plus haute antiquité jusqu'à ce jour. To serve as a Supplement to the Description of the Aerostatic Experiments of Mr. Faujas de Saint-Fond. Paris: Chez Cuchet, 1784. First edition, in-8; viii, 143p, [1p. Errata and Omissions, Approval]. Good uniform modern binding in brown half calf, spine ribbed, gilt fillets and title, cold irons, paper boards with glue for the 3 volumes. Nice set, despite some foxing or soiling to the title pages of the first and third volumes. Rare set of these three fundamental works in first edition. In Annonay en Vivarais, the brothers Joseph and Etienne Montgolfier released on June 4, 1783 a balloon inflated by the smoke of a wet straw fire. The geologist Faujas de Saint-Fond was present among the notables invited to this first public experiment. In Paris on August 27th, a balloon inflated this time with hydrogen was launched from the Champ de Mars in front of 200,000 people by Jacques Charles and the Robert brothers. Then on September 19, in Versailles, in front of the king and his court, the first ascent took place with a rooster, a duck and a sheep. Finally, on November 21, at the Château de la Muette, Pilâtre de Rozier and the Marquis d'Arlandes flew over Paris for 25 minutes, and after an ascent of about a thousand meters landed safely on the Butte-aux-Cailles south of Paris. Faujas de Saint-Fond, one of the most fervent supporters of the new invention, will be the enthusiastic chronicler of these exploits, which gave rise to multiple experiments in the years that followed. Pilâtre de Rozier was the first man to die in aerial service, during an attempt to cross the English Channel on June 15, 1785. In French in the text, 175. PMM 229. Quérard III, 68.
