Jean-François Pilâtre de Rozier (30 March 1754 - 15 June 1785) was a French chemistry and physics teacher, and one of the first pioneers of aviation. He and the Marquis d'Arlandes made the first manned free balloon flight on 21 November 1783, in a Montgolfier balloon. He later died when his balloon crashed near Wimereux in the Pas-de-Calais during an attempt to fly across the English Channel. He and his companion, Pierre Romain, became the first known fatalities in an air crash.
