Pavel Sergeevich Aleksandrov

Born 25 Apr 1896; died 16 Nov 1982 at age 86.Soviet mathematician who made important contributions to the field of topology (the study of related physical or abstract elements that remain unchanged under certain distortions) and one of the founders of the theory of compact and bicompact spaces. Aleksandrov introduced many of the basic concepts of topology, such as the notion that an arbitrarily general topological space can be approximated to an arbitrary degree of accuracy by simple geometric figures such as polyhedrons. Giving support to international cooperation, he supervised the publication of an English-Russian dictionary of mathematical terminology (1962).
