Lincoln–Kennedy coincidences urban legend

Summary

There are many coincidences with the assassinations of U.S. presidents Abraham Lincoln and John F. Kennedy, and these have become a piece of American folklore. The list of coincidences appeared in the mainstream American press in 1964, a year after the assassination of John F. Kennedy, having appeared prior to that in the GOP Congressional Committee Newsletter. In the 1970s, Martin Gardner examined the list in an article in Scientific American, pointing out that several of the claimed coincidences were based on misinformation. Gardner's version of the list contained 16 items; many subsequent versions have circulated much longer lists.
