Arthur C. Cope (June 27, 1909 – June 4, 1966) was an American organic chemist and member of the United States National Academy of Sciences.
At Bryn Mawr, Cope also developed a reaction involving the thermal rearrangement of an allyl group which eventually became known as the Cope rearrangement.
In 1941, Cope moved to Columbia University where he worked on projects associated with the war effort including chemical warfare agents, antimalarial drugs, and treatments for mustard gas poisoning.
In 1945, he moved to the Massachusetts Institute of Technology to become the head of the Department of Chemistry.
Today, the Arthur C. Cope Award, in honor of his memory, is given out annually by the American Chemical Society to the most outstanding organic chemist.
