Dan Asimov presented a...
chess problem that I think I first saw in a Martin Gardner column of almost 40 years ago.
May 1973. Gardner wrote: "The philosopher-mathematician-logician Raymond Smullyan invented this elegant chess problem when he was a student at the University of Chicago in 1957. He showed it to his friend William Browder, now a distinguished mathematician at the university, who passed it on to his father, Earl Browder, former head of the Communist Party in the U.S. and an ardent chess player. The father sent it to the Manchester Guardian, where it was inadvertently published without mentioning Smullyan."
