The Missing Brain in the Kennedy Archives
During John F. Kennedy’s autopsy, doctors removed his brain for examination and preservation. It was kept with other medical evidence from the assassination—material that could help investigators understand the wounds and reconstruct the shooting. But the brain itself later vanished from federal custody. Its whereabouts remain unknown.
How the Evidence Disappeared
The brain and other autopsy materials were transferred to the National Archives, where they were supposed to be preserved as part of the official record. When archivists took an inventory in 1966, they found that the brain was missing. Some related materials, including tissue slides and photographs, also disappeared from the collection at different points, though the brain’s loss is the most striking gap.
The records do not establish who removed it or exactly when. Robert F. Kennedy, the president’s brother, has been associated with the possibility that the family arranged its removal, but that explanation has never been confirmed. Without a documented chain of custody, the gap has resisted a definitive account.
Why Its Absence Still Matters
The missing brain became especially consequential because later disputes about the assassination relied on interpreting medical evidence. Without the organ, researchers cannot independently examine it or use it to settle questions about the president’s injuries. The loss does not itself prove a conspiracy; it leaves a basic, unsettling question unanswered: what happened to a piece of evidence that the government was meant to keep?
