English chemist, mathematician, electrician, astronomer and geologist. He has been called the “Newton of Chemistry.” He wrote only a few papers in the “Philosophical Transactions” between 1766 and 1809. His most notable achievement was his demonstration in 1781 of the composition of water. James Watt also reached the same conclusion about the same time. He ascertained that hydrogen air is at least twelve times lighter than common air, 1777.

Nymphs! your soft smiles uncultured man subdued,
And charm’d the savage from his native wood;
You, while amazed his hurrying Hordes retire
From the fell havoc of devouring Fire.
Taught the first Art, with piny roads to raise,
By quick attrition, the domestic blaze,
Fan with soft breath, with kindling leaves provide,
And list the dread destroyer on his side.

—Botanic Garden: Dr. Darwin

Man carries the world in his head, the whole
astronomy and chemistry suspended in a thought.
Because the history of nature is charactered
in his brain, therefore is he the prophet and
discoverer of her secrets.

—Nature: Emerson
