Walter G. Muir (1905 – December 29, 1999) was a correspondence chess player and former secretary of the ICCF U.S.A. Walter Muir was also a philanthropist and benefactor, and former president of the Roanoke Valley Chess Club.
"It is probably not an understatement to say that Walter Muir has been the single most influential person in the development of correspondence chess in the United States.
He has been a dominant force in postal play on a national and international level for almost five decades.
In a short biography published by the US Chess Federation, it said: "Nine times Canadian Correspondence Chess Association Champion (1928, 1932, 1933, 1934, 1935, 1936, 1939, 1942), twice British Overseas CC Champion, 16 time champion of the Illinois CCA, winner of nine ICCF Master Tournaments, qualified seven times for ICCF World Championship second-round play, and played on four Olympiad teams for the United States.
