Andrey Leman

Andrey Aleksandrovich Leman (Russian: Андрей Александрович Леман, 1940–2012) was a Soviet mathematician and computer scientist who is known for the development of the Weisfeiler Leman graph isomorphism test together with Boris Weisfeiler published in 1968.^[1] He contributed to the chess computer Kaissa, which was the winner of the world's first chess tournament between computer programs in 1974.^[2] In his youth he successfully participated in math Olympiads (Московская математическая олимпиада [ru]) becoming a jury member for the Moscow Mathematical Olympiad^[3]^: 1940 in the 1960s. He also coedited a book for preparation of future olympiad participants.^[4] He contributed to the first Soviet database INES which was used ubiquitously in the USSR and for which he received the USSR Council of Ministers Prize.^[5] In 1990 he emigrated into the US where he continued to work as a software developer. He contributed to the Cuneiform OCR in the 1990s which was used by notable companies such as Oracle, IBM, and Samsung.
