Weisberg, an Office of Strategic Services officer during World War II, U.S. Senate staff member and investigative reporter, devoted 40 years of his life to researching and writing about the Kennedy and King assassinations. His first book, Whitewash: The Report on the Warren Report (1965), was the first critical study of the government's official version of what happened in Dallas on Nov. 22, 1963. Seven of the eight books Weisberg published after Whitewash were about the Kennedy assassination. Over time, Weisberg became recognized, both nationally and internationally, as the dean of writers critical of the official version of the JFK assassination known as the Warren Commission Report. Harold Weisberg donated the world's largest accessible private collection of government documents and public records relating to the assassination of President John F. Kennedy to Hood College and the Beneficial-Hodson Library at Hood College, which donated a copy to the National Security Internet Archive.
