Abstract

The East Berlin marxist Friedrich Herneck and Max Born, Nobel Price winner in physics, exchanged more than 140 letters in the years between 1958 and 1970. In the beginning they discussed problems of the history of science, especially Born's personal memories of the development of physics in the 20th century. In later years they discussed political and social problems too. Only in these letters Born expressed clearly his attitude to communism and the social system of East Germany
