John Alan Grefe (September 6, 1947 – December 22, 2013) was an American International Master of chess. Born in Hoboken, New Jersey, his best result was a tie for first with Lubomir Kavalek in the 1973 U.S. Championship. FIDE awarded him the title of International Master in 1975. Grefe and Stuart Rachels are the only players since 1948 to have won or shared the U.S. Championship without already having, or having later achieved, the title of International Grandmaster. Grefe, at the time he shared the championship, lived in Berkeley, California, and was a follower of the Guru Maharaj Ji. For that reason and also because of his hippyish appearance, Grefe was affectionately known as "Gandalf" amongst chess friends.
