He is best known as the creator and chief organizer of the Tournament of the Towns.^{[1]} For his work he was awarded the Paul Erdős award in 1992.^{[2]}
Konstantinov was born and grew up in Moscow, Soviet Union. He graduated from the Physics Department of the Moscow State University in 1954, and later received a Ph.D. in physics.
In the 1950s he started a math circle in Moscow University and since 1960s in a number of Moscow high schools. He continued working with schools developing special classes with mathematics concentration and individual approach to learning. His students went on to win mathematics competitions on all levels and dozens of them became well known mathematicians.
In 1978, Konstantinov started the Lomonosov tournament, a multisubject science competition. This tournament is continued every year since then. In 1980, he started the international Tournament of the Towns which is now organized in over 150 towns in 25 countries.^{[3]}^{[4]}
In 1990 Konstantinov was one of the founders of Independent University of Moscow, one of the leading institutions of higher learning in mathematics in Russia.^{[5]}
