The Russian American sociologist and social philosopher Pitirim A. Sorokin (1889-1968), an ardent opponent of Communism, but an early supporter of the Russian Revolution, served during the Russian Revolution as secretary to Prime Minister Alexander Kerensky, who was a leader in the Russian Constituent Assembly.
After the October Revolution, Sorokin continued to fight communist leaders, and was arrested by the Bolshevik regime several times before he was eventually condemned to death. After six weeks in prison, he was set free and went back to teaching at the University of St. Petersburg. In 1918, he went on to become the founder of the sociology department at the University of St. Petersburg. In 1922, Sorokin was again arrested and this time exiled by the Soviet government. He emigrated in 1923 to the United States and was naturalized in 1930. Sorokin was professor of sociology at the University of Minnesota (1924–30) and at Harvard University (1930–59).
