The Czech philosopher Jan Patocka (1907-1977), who studied with Husserl and Heidegger, is widely recognized as the most influential thinker to come from postwar Eastern Europe. Refusing to join the Communist party after World War II, he was banned from academia and publication for the rest of his life, except for a brief time following the liberalizations of the Prague spring of 1968. Joining Vaclav Havel and Jiri Hajek as a spokesman for the Chart 77 human-rights declaration of 1977, Patocka was harassed by authorities, arrested, and finally died of a heart attack during prolonged interrogation.
