Jacques Charles (1746-1823), French chemist, physicist, and aeronaut, born in Beaugency, Loiret. In 1783 he made the first balloon using hydrogen gas and ascended to a height of nearly 3 km (2 mi). In 1787 he discovered the relationship between the volume of a gas and its temperature, known variously as Gay-Lussac's law or Charles' law. He was elected to the French Academy in 1785.
