Ward V. Evans (1880 - 1957) was a chemist who served as a professor at Northwestern University and Loyola University Chicago. He was known as one of three members of the commission which revoked the security clearance of J. Robert Oppenheimer. Evans was the only member who voted to allow Oppenheimer to retain his security clearance, stating that failure to clear Oppenheimer would be "a black mark on the escutcheon of our country.".
