"I have known Dr. Sturdivant for fifteen years. During the period 1927-1930 he carried on graduate work in chemistry at the
California Institute of Technology under my direction, and since 1930 he has worked continuously as Research Fellow, Senior
Fellow in Research, and Assistant Professor of Chemistry. Throughout this time I have been in very close contact with ihm.
I have complete confidence in his honesty, integrity, loyalty to the United States of America. I rate him as the most reliable
and trustworthy man that I know."
Linus Pauling. Letter to George Kistiakowsky. May 27, 1942.
