Robert J. Groden (born November 22, 1945) is an American author who has written extensively about conspiracy theories regarding the assassination of U.S. President John F. Kennedy. His books include The Killing of a President: The Complete Photographic Record of the JFK Assassination, the Conspiracy, and the Cover-up; The Search for Lee Harvey Oswald: A Comprehensive Photographic Record; and JFK: The Case for Conspiracy (shorter version than his 1975 co-authored book). Groden is a photo-optics technician who served as a photographic consultant for the House Select Committee on Assassinations. A harsh critic of the Warren Commission, he also testified at the 1975 United States President's Commission on CIA activities within the United States (sometimes referred to as the Rockefeller Commission). Early life Groden attended Forest Hills High School in Queens, New York, leaving in the 11th grade. He served in the Army starting in 1964, and first became interested in the assassination of John F. Kennedy that same year. Career After Groden returned from his Army tour in 1967, he became a photo technician working in a New York City motion picture processing lab; he had special expertise blowing up 8mm film for theatrical distribution. In 1969 the company did a large job processing film for the documentary Woodstock; and because of that work, it was awarded a contract from Life to work on the Zapruder film, the 27-second home movie captured by Abraham Zapruder of the Kennedy assassination. Groden worked on that project and made an additional unauthorized copy of the film, which he then kept hidden for several years, fearing not only the legal ramifications but also for his own life. In 1973, Groden showed the film to a symposium of assassination researchers at Georgetown University. In February 1975, Groden and Stephen Jaffe, an investigator for New Orleans District Attorney, Jim Garrison, testified before the Rockefeller Commission, chaired by Vice President Nelson Rockefeller, CIA activities related to the assassination of President Kennedy. Groden achieved his first national exposure on March 6, 1975, when he and Dick Gregory were on Good Night America, a late-night TV program hosted by Geraldo Rivera, and they showed Groden's copy of the Zapruder film. It was the first time ever it was shown in motion to a national TV audience. In 1975, Groden co-authored, with F. Peter Model, the book JFK: The Case for Conspiracy. In the late 1980s, Groden was a consultant
