American chemist and Professor at Harvard College. He rendered the inductive methods of experimental science a means of liberal culture in the college, and also in the preparatory school. His investigation of the atomic weight of antimony (1880) was one of the most brilliant and perfect pieces of chemical work ever executed. His “New Chemistry” was the earliest exposition of a consistent system of chemistry based on the principles of molecular mechanics. Most of his contributions to chemical science have been collected in “Chemical and Physical Researches” (1881).

For the world was built in order,
And the atoms march in tune;
Rhyme the pipe, and time the warder,
The sun obeys them and the moon.

—Monadnock: Emerson

Ah me! Experience (so we’re told),
Time’s crucible, turns lead to gold;
Yet what’s experience won but dross,
Cloud-gold transmuted to our loss?
What but base coin the best event
To the untried experiment?

—A Familiar Epistle to a Friend: Lowell
