What type of Soviet delegation at the Solvay Conferences?

Soviet scientists have been represented on the Scientific Committee of the International Solvay Institute for Physics since 1930 by the physicist Abram Ioffe as a replacement for Martin Knudsen.

Following George Gamow’s defection in 1933, the Soviet Union decides to involve itself in the choice of its representatives at the Conferences on Physics, a decision that complicates the task of the International Scientific Committee.

In the late 1950s already, the possibility is raised of letting a Soviet representative join the Scientific Committee of the Solvay Institute for Chemistry. The name of Alexander Nesmeyanov is put forward

Although this idea is not approved unanimously, Alexander Nesmeyanov becomes the first Soviet member of the Scientific Committee for Chemistry in 1967.
