From Wikipedia, the free encyclopedia

Boris Mikhailovich Koyalovich (Koyalovitch, Kojalovich, Kojalowitsch, Kojałowicz) (May 2, 1867 – December 29, 1941) was a mathematician and chess master from the Russian Empire and later the Soviet Union.

Biography[edit]

Koyalovich was born on May 2, 1867.[1] He was a professor of mathematics at the Saint Petersburg State Institute of Technology.[2][3] In 1924 he was an Invited Speaker of the ICM in Toronto.[4] In 1930, he developed the special theory of limitants.[5]

Koyalovich lived and died in St. Petersburg (also known as Petrograd and Leningrad during his lifetime) on December 29, 1941.[6] He played in many of the city's chess tournaments, taking 4th place in 1901 (Sergey Lebedev won), 3rd in 1902 (Mikhail Chigorin and Alexander Levin won),[7] and 11th in 1903 (Grigory Helbach, Krzyzanowski and Emmanuel Schiffers won). In 1904 he competed at three events, tying for 4-5th in one (Eugene Znosko-Borovsky won), taking 5th in another (Chigorin won), and winning the third. He tied for 4-5th in 1905 (Chigorin won), tied for 8-9th in 1906 (Simon Alapin won), and tied for 5-6th in 1907 (Sergey von Freymann won).[8]

He played in a friendly match St. Petersburg vs. Moscow in 1911 (won a game against Parfenov on board 7),[9] and won a game against Alexander Alekhine in St. Petersburg in April 1912.[10]

After World War I, he tied for 5-9th at Petrograd 1921 (R.R. Platz won), took 6th at Novgorod 1923/24 (Ilya Rabinovich won), took 9th at Leningrad 1925 (Solomon Gotthilf won), and tied for 6-7th at Leningrad 1925 (Efim Bogoljubow and Peter Romanovsky won).[11]
