David Abrahamsen
David Abrahamsen (June 23, 1903 – May 20, 2002) was a Norwegian forensic psychiatrist, psychoanalyst, and author who wrote analyses of Richard M. Nixon and David Berkowitz. He was born in Trondheim, Norway and trained in Europe. Abrahamsen came to the United States in 1940.
He became a student of criminal psychopathology while he was affiliated with prisons in New York and Illinois. He lectured at a number of important hospitals. Abrahamsen became interested in the Son of Sam murders, which began in 1976 and would proceed to document the life of David Berkowitz.[1]
Abrahamsen's paper, A Study of Lee Harvey Oswald: Psychological Capability of Murder, was published in the Bulletin of the New York Academy of Medicine, in October 1967. His book, Our Violent Society, came out in 1970, a Funk & Wagnalls' publication.[2]
