As the 1960s moved forward, Linus Pauling’s interest in contributing to an academic circle that resolutely rejected the Vietnam War continued to strengthen. A participant in several past petitions, Pauling co-authored another such document in June 1967, a “Scientists’ Appeal for Vietnam,” signed by a collection of scientific all stars including Nobel laureates Pauling, Lord John Boyd Orr, Dorothy Crowfoot Hodgkin, Alfred Kastler, André Michel Lwoff, C.F. Powell, Bertrand Russell, R.L.M. Synge, and Albert Szent-Györgyi. Additional signatories included Pauling’s close friend J.D. Bernal, an influential x-ray crystallographer and peace activist; neurologist and president of the Association of Scientific Workers Harry Grundfest; Soviet biochemist Alexander Oparin; and an Indian scientist and activist, S. Hussain Zaheer.
