From "Karl Marx Plays Chess" by Andy Soltis:

"Bobby was an excellent blindfold player and, on one memorable occasion, New
Year's Eve 1963, demonstrated this skill against international master
William Addison. They played a series of five-minute games. Fischer did so
without sight of the board _and_ gave odds of pawn and move to an opponent
good enough to qualify year after year for the U.S. Championship. Aft5er a
number of games the two men came out roughly even, according to eyewitness
Brady."

Fischer of all people was one of those. He actually stated that he
could not visualize a board in his mind. Koltanowski was famous for
that ability to visualize perfectly a chessboard in his mind and play
simuls blindfolded. I suppose it is something unique you either have
or you don't. Pillsbury also could visualize many boards and play.
Some GM's can do it to a certain extent but not at the level of
Pillsbury or Kolty. There are others but I don't know offhand.
