Sonnenfeldt, Richard Wolfgang

Inventor, executive and chief interpreter at the Nuremberg trials

Nazi Germany introduced the Nuremberg Laws in 1935. The laws forbade marriages and intercourse between Jews and Germans and the employment of German females under 45 in Jewish households. The laws also declared that only those of German or related blood had the right to be Reich citizens. Richard Wolfgang Sonnenfeldt was born in a Jewish family in 1923, Berlin. In 1938 his mother could deliver him with his younger brother to a boarding school in England. When World War II started, Sonnenfeldt was interned in England as an enemy alien, sent to a prison in Australia and then released. After a short stay in India, he arrived in Apr 1941 in the United States where he met his family again in Baltimore.

Sonnenfeldt became a U.S. citizen and was drafted into the US Army in 1943. The army sent him as a soldier back to the frontlines in Europe. He participated in the Battle of the Bulge (16 Dec 1944 – 25 Jan 1945), the last major German offensive on the Western Front in the forested Ardennes. In Apr 1945 Sonnenfeldt entered the liberated Dachau concentration camp. There he saw the many dead bodies and near-dead survivors.

After Nazi Germany surrendered, Sonnenfeldt served as Sergeant in Austria where General William J. Donovan recruited him to be his personal interpreter. Sonnenfeldt spoke fluently German and English. After the war Donovan became the first deputy of U.S. Supreme Court Justice Robert H. Jackson. President Truman had appointed Jackson as U.S. Chief of Counsel for the prosecution of Nazi war criminals. Sonnenfeldt became the principal interpreter for American prosecutors at the Nuremberg war crimes trials. He helped interrogating notorious leaders of the Third Reich, including Rudolf Hess, Hermann Goering and Albert Speer.
