Comité de défense des ouvriers
Edelman's hospital upbringing had proven invaluable in the Warsaw Ghetto. After World War II, he studied at Łódź Medical School and became a noted cardiologist who invented an original life-saving operation. In 1948 Edelman actively opposed the incorporation of the Bund into the Polish United Workers' Party (Poland's communist party), which led to the communists disbanding the organization. In 1976, he became an activist with the Workers' Defence Committee ("Komitet Obrony Robotników") and later with the Solidarity movement. Edelman publicly denounced racism and promoted human rights.
