In 1950, FIDE awarded the modern grandmaster title to 27 players. Andor Lilienthal, the last survivor among the original grandmasters, died last week at the age of 99.
More on Grandmaster Lilienthal in the ChessBase obituary and Wikipedia article; also see Kasparov's appreciation in My Great Predecessors, Part 4. Frederick Rhine tells me that Lilienthal was one of the last surviving players (and by far the strongest player) with a Morphy number of 3.
There was a moment of silence in Lilienthal's honor before Game 11 of the World Championship yesterday.
