François Laurent d'Arlandes (French pronunciation: ​[fʁɑ̃swa loʁɑ̃ lə vjø daʁlɑ̃d]; 1742 – 1 May 1809) was a French marquis, soldier and a pioneer of hot air ballooning. He and Jean-François Pilâtre de Rozier made the first manned free balloon flight on 21 November 1783, in a Montgolfier balloon. D'Arlandes was born in Anneyron in the Dauphiné. He met Joseph Montgolfier at the Jesuit college of Tournon. He became an infantry officer in the French royal guard. D'Arlandes proposed a flight to cross the English Channel in 1784, but the plan came to nothing.
