Jan Patočka was a Czech philosopher. Having studied in Prague, Paris, Berlin, and Freiburg, he was one of the last pupils of Edmund Husserl and Martin Heidegger. In Freiburg he also developed a lifelong philosophical friendship with Husserl's assistant Eugen Fink. Patočka worked in the Czechoslovak Socialist Republic for almost his entire career, but never joined the Communist Party and was affected by persecution, which ended in his death as a dissident spokesperson of Charter 77.

Martin Heidegger was a German philosopher who is best known for contributions to phenomenology, hermeneutics, and existentialism. He is often considered to be among the most important and influential philosophers of the 20th century.
