From Wikipedia :

Richard Kenneth Guy (born 30 September 1916) was a British mathematician and professor emeritus in the Department of Mathematics at the University of Calgary.[1] He was known for his work in number theory, geometry, recreational mathematics, combinatorics, and graph theory.[2][3] He was best known for co-authorship (with John Conway and Elwyn Berlekamp) of Winning Ways for your Mathematical Plays and authorship of Unsolved Problems in Number Theory.[4] He had also published over 300 papers.[5] Guy proposed the partially tongue-in-cheek “Strong Law of Small Numbers,” which says there are not enough small integers available for the many tasks assigned to them – thus explaining many coincidences and patterns found among numerous cultures.[6] For this paper he received the MAA Lester R. Ford Award.[7]

From 1947 to 1951 Guy was the endings editor for the British Chess Magazine.[40] He is known for almost 200 endgame studies. Along with Hugh Blandford and John Roycroft, he was one of the inventors of the GBR code (Guy–Blandford–Roycroft code), a system of representing the position of chess pieces on a chessboard. Publications such as EG magazine use it to classify endgame types and to index endgame studies.[41]
