William Bruce Pitzer

William Bruce Pitzer (April 13, 1917 - October 29, 1966) was an officer of the United States Navy whose death is speculated to have had some connection with the assassination of John F. Kennedy.

After discharge in 1939, he worked for three years as chief technologist at the Episcopal Ear, Eye and Nose Hospital.

Pitzer's alleged possession of autopsy-related film and photographs is briefly discussed in the television documentary The Men Who Killed Kennedy.

Pitzer's death occurred the same day that the Kennedy family agreed, through their attorney, to release to the National Archives several items related to the autopsy of the fallen president, including photographs and x-rays.

Dennis David's recollections of the autopsy and of Pitzer's materials were first made public in an anonymous 1975 interview with the Waukegan, Illinois News Sun.
