James Holmes Sturdivant (1906–1972) was a chemist who worked for several years as the main research assistant to Linus Pauling at Caltech, starting in 1927.[1][2][3][4][5][6][7] He co-authored some seminal papers with Pauling,[8][9][10][11] and was co-advisor of Robert Eugene Rundle.[12]

Personal history

James Sturdivant was born in Greenville, Texas, on June 22, 1906. He got is B. A. degree at the University of Texas in 1926, his M. A. in 1927, and his Ph. D. at Caltech in 1930, advised by Pauling.[13] By December 1954 he was living at the Athenaeum, 551 South Hill Avenue, Pasadena.[13]

Sturdivant died in Pasadena on April 21, 1972, at the age of 66, survived by his wife Arletta.[1]

Work

He was instructor in Mathematics at the University of Texas from 1926 to 1927. At Caltech, he held position of Teaching Fellow (1927-1930), Research Fellow (1930-1935), Senior Fellow in Research (1935-1938), and Assistant Professor (since 1938).[13] As a professor, he taught X-ray crystallography.[1]

One of the first results of the collaboration with Pauling, soon after is hiring in 1927, was the elucidation of the structure of the titanium mineral brookite, that led Pauling to develop his theory of coordination bonding.[8]

Another important result of their collaboration was the partial elucidation of the molecular structure of certain compounds discovered by Liebig in the 1830s, including melon, melem, cyameluric acid, and hydromelonic acid. They realized that those compounds had a common core with formula C
6N
7, consisting of three fused triazine rings, now known as the heptazine core.[9]

Among many other projects, Sturdivant helped Pauling to develop a device to measure the concentration of oxygen in gases.[10] The patent for the device was assigned to the two and to Reuben Wood, and was donated to the on condition that the authors receive a fraction of any revenue coming from it.[14]

As manager of the Caltech instrument shop, Sturdivant helped Pauling and Corey build their prototypes of the space-filling molecular models.[15]

He was a member of the American Chemical Society, the American Physical Society, and the American Crystallographic Association.[1]

A lecture hall at Caltech is named "J. Holmes Sturdivant".[16]

Quote: "Professor Sturdivant, an American-borne citizen who took his Ph.D. with me in 1930 and has continued as a member of our department since then, is a very gifted man, with ability in the field of instrumental design as well as along general scientific lines. He has designed all of our x-ray apparatus built in recent years. In addition he is in charge of the chemistry department instrument shop here. Dr. Sturdivant is thoroughly familiar with the details of construction and operation of the oxygen instrument, and would be the best possible man with whom to discuss the possibilities of application of the instrument in various ways and of its special design for special purposes. [...] I have full confidence in his loyalty to the United States. I have known Professor Sturdivant intimately for fourteen years." Accessed on 2020-05-10.
