Richards, Theodore W. (1868-1928). An American chemist born in Germantown, PA. He was the first American to receive the Nobel Prize in chemistry. He studied chemistry at Haverford and Harvard, with a doctorate in chemistry from Harvard where he later became Erving Professor of Chemistry. An outstanding experimental chemist, his major interests were atomic weights, thermochemistry, and thermodynamics. He was also a brilliant teacher. He was president of the ACS in 1914, and the recipient of many honorary awards, including the Davy, Faraday, and Gibbs medals. 

Richards, Theodore William (1868-1928) American chemist who determined with great accuracy the atomic weights of 25 elements. This led to the discovery of natural isotopes of elements, each of which has a slightly different weight because of the different number of neutrons. In 1905, he introduced the adiabatic calorimeter, an instrument that measured the heat rise from combustion without error from loss or gain of heat. He received the Nobel Prize in chemistry in 1914.

At Harvard, Theodore William Richards, like Noyes, inherited a course in theoretical chemistry. He renamed it physical chemistry. However, he cautioned students that the molecular kinetic hypotheses might prove ephemeral, and, to the young Lewis s consternation, Richards showed contempt for the notion of chemical bonds. "Twaddle about bonds A very crude method of representing certain known facts about chemical reactions. A mode of representation] not an explanation. "68 It was not so much that Richards sided with energeticists against kinetic and mechanical representations, but he did have a distrust of mathematical formulations too far removed from the laboratory. When J. Robert Oppenheimer enrolled in Richards s course in physical chemistry in 1925, he pronounced it "a great disappointment,. .. a very meager hick course.. . . Richards was afraid of even rudimentary mathematics."69 Thus, physical chemistry by no means necessarily meant mathematical chemistry.

American chemist Theodore Richards (1868-1928) discovers lead of varying mass (due to different isotopes). 

Theodore William Richards, 1868-1928. Director of the Wolcott Gibbs Memorial Laboratory at Harvard University. The precision of his atomic weight determinations has never been surpassed. He discovered the anomalous atomic weights of lead from radioactive minerals.
