Word History

Etymology

Noun

borrowed from French, "type of pressure cooker," short for marmite autoclave, probably meant to be understood as "cooking pot that locks itself (by internal pressure)," from auto- auto- + -clave, borrowed from Latin clāvis "key" — more at clavicle

Note: The word was presumably coined by the French politician, educator and inventor Pierre Alexandre Lemare (1766-1835), who filed for a patent (brevet d'invention) on the autoclave in 1820. See Dictionnaire chronologique et raisonné des découvertes, inventions … en France … de 1789 à la fin de 1820, tome premier (Paris, 1822), pp. 485-87.
