Martin Kreuzer (born 1962, Regensburg, Germany), is a German Grandmaster of Correspondence Chess and a Mathematics professor.
Kreuzer did his undergraduate studies in Mathematics at the University of Regensburg, located on the Danube River in Bavaria. He moved to the United States and completed his doctorate at Brandeis University in Boston. Next came a post-doctoral fellowship at Queen's University in Kingston, Ontario, Canada, from 1989 to 1991, working in algebraic geometry with Professor Anthony Geramita. He then returned to Germany, and is currently a professor at the University of Passau, researching in cryptography and in computational commutative algebra.
Kreuzer's chess skills have earned him the FIDE Master title for over-the-board play. During his short stay in Canada, he finished fourth at the 1990 Open Canadian Chess Championship at Edmundston, and contributed a fine article on his games there to Chess Canada magazine. He won the Queen's University Championship twice, and represented Queen's in team play. He completed a grand slam of local Kingston events in one season (1990-91), never done by anyone else, before or since, with the Kingston Whig-Standard title, the Queen's U. title, the Kingston Open title, and the Kingston Chess Club title.
He gained the title of International Correspondence Chess Grandmaster[1] (GMC) 1994, from his result in the 1988-95 Von Massow Memorial tournament, where he noted that his favourite game was his win as Black over Werner Metz. Kreuzer played board six in the finals, on the German team which won the 12th Correspondence Chess Olympiad, 1998-2004. A selection of his games can be found at chessbase.com.
