"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.
