Helmut Flieg or Hellmuth Fliegel (10 April 1913 – 16 December 2001) was a German writer, known by his pseudonym Stefan Heym (pronounced [ˈʃtɛfan ˈhaɪm] ). He lived in the United States and trained at Camp Ritchie, making him one of the Ritchie Boys of World War II. In 1952, he returned to his home to the part of his native Germany which was, from 1949 to 1990, the German Democratic Republic (GDR, "East Germany"). He published works in English and German at home and abroad, and despite longstanding criticism of the GDR remained a committed socialist. He was awarded the 1953 Heinrich Mann Prize, the 1959 National Prize of East Germany (2nd class), and the 1993 Jerusalem Prize. Source: Wikipedia (en)
