Leonid Sedov

Leonid Ivanovich Sedov (Russian: Леонид Иванович Седов; 14 November 1907, Rostov-on-Don – 5 September 1999, Moscow) was a Russian physicist who worked as an engineer in the former Soviet space program.

In 1930 Sedov graduated from the Moscow State University, where he had been a student of Sergey Chaplygin, with the degree of Doctor of Physics and Mathematical Sciences. He later became a professor at the university.

During World War II, he devised the so-called Sedov Similarity Solution for a blast wave. In 1947 he was awarded the Chaplygin Prize. He was the first chairman of the USSR Space Exploration program and broke first news of its existence in 1955. He was president of the International Astronautical Federation (IAF) from 1959 to 1961. Until recently, it had been thought that Sedov was the principal engineer behind the Soviet Sputnik project.
