By factitious air, I mean in general any kind of air which is contained any in other bodies in an unelastic state, and is produced from thence by art.
English natural philosopher, and scientist (1731–1810)
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 late…

It only remains that I offer very briefly my own estimate of the character of the Philosopher. Morally it was a blank, and can be described only by a series of negations.
All that needed for its apprehension, more than the pure intellect, or required the exercise of fancy, imagination, affection, or faith, was distasteful to Cavendish.
