Jean-François Pilâtre de Rozier was a French chemistry and physics teacher, and one of the first pioneers of aviation. He and François Laurent 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, thus became the first known fatalities in an air crash.
