Hammond attended Bates College in Lewiston (Maine) with a Bachelor's degree in chemistry , magna cum laude in 1943 and was in 1947 Paul D. Bartlett at Harvard University with the work The inhibition of the peroxide induced polymerization of allyl acetate doctorate . As a post-doctoral student , he was with Saul Winstein at the University of California, Los Angeles . In 1948 he became an assistant professor and later professor at Iowa State University and in 1958 he became a professor of organic chemistry at Caltech , from 1968 as Arthur Amos Noyes professor .

He also held various senior positions at Allied Signal Corporation in Morristown, New Jersey, from the 1970s to 1987 .

The Hammond postulate is named after him (sometimes also Hammond-Leffler postulate). In 1961 he succeeded in rearranging diene compounds under the action of light into cyclobutane derivatives.

In 1994 he received the Glenn T. Seaborg Medal and the National Medal of Science . He received the Priestley Medal (1976), the George A. Olah Award in Hydrocarbon or Petroleum Chemistry, and the James Flack Norris Award (1968). He has multiple honorary doctorates (Gent, Weizmann Institute, Wittenberg, Bates College, Georgetown University, Bowling Green State University). He was a member of the National Academy of Sciences from 1963 and its secretary for foreign affairs from 1974 to 1978. In 1965 he became a Fellow of the American Academy of Arts and Sciences , and in 1956/1957 he was a Guggenheim Fellow .
