Oldřich Černík
Oldřich Černík (October 27, 1921 – October 19, 1994) was a Czechoslovak Communist political figure. He was the prime minister of Czechoslovakia from April 8, 1968 to January 28, 1970. A party official and well-known technocrat, Černík was a strong supporter of the Prague Spring reforms of 1968. In August 1968 he was forced to go to the Soviet Union along with other politicians, and when he returned he asked the Czech people to cooperate with the Soviet Union but promised to continue reforms. After party leader Alexander Dubček was replaced with Gustáv Husák in 1969, Černík publicly  distanced himself from his previous support of reform. It was not enough to prevent him from being forced out as prime minister in 1970; he was expelled from the party soon afterward. He attempted a political comeback in the early 1990s after the end of the communist regime. He died in Prague.
