Something wrong?He isolated hydrogen, weighed the planet, and barely spoke to anyone while doing it. Cavendish treated the natural world like a locked room problem - and solved several that had stumped everyone else.

Born in 1731, Cavendish came to chemistry and physics with a temperament better suited to monasteries than salons: shy, methodical, and uninterested in credit. In 1766 he published a paper describing "inflammable air" - hydrogen - noting its density and the fact that it formed water when burned. Lavoisier would later repeat the work and name the element. Cavendish moved on: atmospheric composition, the synthesis of water, electrical forces, a mechanical theory of heat. His most famous work came late, an experiment so precise it measured the density of the Earth itself, a feat that allowed later scientists to derive the gravitational constant. He died in 1810, having documented the world with a rigor few could match and a public presence almost no one remembered.
