Some scholars speculate that the lumbar brace Kennedy wore towards the end of his life played a role in his death. After Lee Harvey Oswald shot him in the neck, the argument goes, the brace may have pulled Kennedy back into an upright position—placing him back into Oswald’s sights for the second, fatal shot. Perhaps without the brace, he would have slumped forward—and just might have survived. But there’s no way to know, Dowdy and Pait concluded. Still, they wrote, Kennedy’s long struggle with back pain may have helped alter history.
