Henry Cavendish

 

Cavendish is an English chemist who was the first to recognize hydrogen gas as a distinct substance.  He also described the composition of water .In order to establish that hydrogen gas was a substance entirely different from ordinary air, he calculated their densities as well as the densities of several other gases.  He also  the first that showed that water is composed of oxygen and hydrogen.  He measured heats of fusion and evaporation as well as specific heats and those of the mixing solutions in water.

*For an amazing connection between history and science, read Stephen Jay's Gould's first chapter of Bully for Brontosaurus(1991). The policy behind the The Treaty of Ghent in 1814 was set by Robert Castlereagh, who had survived a duel, only to commit suicide later in life. His nephew, Fitzroy, who also suffered from manic depression, was the captain of the Beagle. The latter hired Charles Darwin because he wanted a social companion for the mentally-demanding voyage. Contrary to popular myth, Darwin was not hired as the ship's naturalist. So if the shadow of Fitzroy's uncle's suicide had not loomed over him, Darwin may never have been hired and may never have been inspired to explain evolution.
