Nikolai Shvernik
Acting
Nikolai Shvernik was a Soviet politician who served as the second chairman of the Presidium of the Supreme Soviet (head of state) from 1946 until 1953. Though he was the head of state, Shvernik had very little power as Joseph Stalin, the premier at the time, had most of the power due to his position as general secretary of the CPSU, the de facto leader.
