C. F. H. (Charles Francis Hitchcock) Allen

Born in Milford, New Jersey, in August 1895, Charles Francis Hitchcock Allen studied at Boston University, earning an A.B. in 1919 and an A.M. in 1920, and later completed a Ph.D. at Harvard University in 1924. He built his career in chemistry during a period when organic research was expanding quickly, and his early published work included Meta Toluene Sulphonic Acid and Related Compounds.

Allen became especially associated with Organic Syntheses, where he served as the first Secretary to the Editors from 1929 to 1937 and later continued on its advisory board. That role suited his reputation for careful scientific organization and clear presentation, helping useful laboratory methods reach working chemists in a dependable form.

As an author, he is remembered for substantial reference works on heterocyclic chemistry, including volumes in The Chemistry of Heterocyclic Compounds. He died on August 31, 1979. A suitable confirmed portrait image was not found from the sources reviewed during this conversation.
