Richard Kenneth Guy, (September 30, 1916  March 9, 2020 ^{[2]})
was a British Canadian mathematician, and Professor Emeritus in the Department of Mathematics at the University of Calgary. His research interests included combinatorial games ^{[3]}, enumerative combinatorics, combinatorial geometry, number theory and graph theory ^{[4]}. He studied mathematics at the University of Cambridge, from 1941 to 1949 he was high school teacher at Goldsmiths College and then taught at the University of Malaya, from 1956 at Indian Institute of Technology in New Delhi, and since 1962 at the University of Calgary ^{[5]}.
Guy was chess player and composer of chess endgame studies, and was along with John Roycroft and Hugh Blandford coinventor of the GuyBlandfordRoycroft code for classifying studies. In 1939, he started the Stockport Grammar School Chess Club ^{[6]}, and served as endgame study editor for the British Chess Magazine from 1948 to 1951 ^{[7]}.
