Georgy Maximovich Adelson-Velsky (Russian: Гео́ргий Макси́мович Адельсо́н-Ве́льский; name is sometimes transliterated as Georgii Adelson-Velskii) (8 January 1922 – 26 April 2014) was a Soviet and Israeli mathematician and computer scientist.

Born in Samara, Adelson-Velsky was originally educated as a pure mathematician. His first paper, with his fellow student and eventual long-term collaborator Alexander Kronrod in 1945, won a prize from the Moscow Mathematical Society.[1] He and Kronrod were the last students of Nikolai Luzin, and he earned his doctorate in 1949 under the supervision of Israel Gelfand.[2]

He began working in artificial intelligence and other applied topics in the late 1950s.[1] Along with Evgenii Landis, he invented the AVL tree in 1962. This was the first known balanced binary search tree data structure.[3]

Beginning in 1963, Adelson-Velsky headed the development of a computer chess program at the Institute for Theoretical and Experimental Physics in Moscow. His innovations included the first use of bitboards (a now-common method for representing game positions) in computer chess.[4] The program defeated Kotok-McCarthy in the first chess match between computer programs, also in 1966,[4] and it evolved into Kaissa, the first world computer chess champion.[5]

In August 1992, Adelson-Velsky moved to Israel, and he resided in Ashdod.[1]

Adelson-Velsky died on 26 April 2014, aged 92, in his apartment in Giv'atayim, Israel.[6]
