Howard Morland (born September 14, 1942) is an American journalist and activist against nuclear weapons who, in 1979, became famous for apparently discovering the "secret" of the hydrogen bomb (the Teller–Ulam design) and publishing it after a lengthy censorship attempt by the Department of Energy (United States v. The Progressive). Because of some similarities in experience, he became outspoken in the protest against detention of Mordechai Vanunu.
