Leonid I. Sedov

Leonid Ivanovitch Sedov (14 November 1907 – 5 September 1999) was a leading physicist of the Soviet Union.

During WW2 he devised the so-called "Sedov Similarity Solution" for a blast wave [2] . He was also 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.
