Jewish emigrants from Nazi Germany to France

Hilde Neumann (born Hilde Martha Betty Rosenfeld: 13 April 1905, in Berlin-Karlshorst – 11 September 1959, in Berlin) was a German lawyer.She was politically leftwing and of Jewish provenance: she spent the Nazi years in exile. In 1947 she returned to Berlin and resumed her political focus, becoming a senior legal official in the Socialist Unity Party (Sozialistische Einheitspartei Deutschlands / SED), which by 1949 had become the ruling party of the German Democratic Republic (East Germany) which was formally established in October of that year. She also served as editor in chief of "Neue Justiz", an East German monthly specialist journal concerned with legal matters.

Selmar Aschheim (4 October 1878 – 15 February 1965) was a German gynecologist who was a native resident of Berlin.
Born into a Jewish family, in 1902 he received a doctorate of medicine in Freiburg, and later became director of the laboratory of the Universitäts-Frauenklinik at the Berlin Charité. In 1930 Aschheim attained the chair of biological research in gynecology at the University of Berlin. In 1933 he fled Nazi Germany and moved to Paris, where he worked in medical research at the Hôpital Beaujon.
Aschheim was a specialist concerning gynecological histology and hormone research. In 1928 with endocrinologist Bernhard Zondek (1891–1966), he isolated the gonadotropic hormone known as human chorionic gonadotropin (hCG), which was discovered in the urine of pregnant women. From their research the "Aschheim-Zondek test" for pregnancy was created, which involved injection of a patient's urine into an immature laboratory mouse. If the rodent displayed an estrous reaction, it represented a positive indication of pregnancy.
The two doctors published the findings of the hormone in a treatise titled Das Hormon des Hypophysenvorderlappens. At the time they believed that the gonadotrophin was produced by the anterior pituitary, however further research in the 1940s demonstrated that the placenta was responsible for the elaboration of the hormone.

Erwin Anton Gutkind (20 May 1886, Berlin – 7 August 1968, Philadelphia), was a German-Jewish architect and city planner, who left Berlin in 1935 for Paris, London and then Philadelphia, where he became a member of the faculty of the University of Pennsylvania. Of his work in Germany, all but one building remains and as of 2013 most if not all have historical protection orders on them. Some of them have also been restored.

Hans Sahl (born Hans Salomon, 20 May 1902 in Dresden – 27 April 1993 in Tübingen) was a poet, critic, and novelist who began during the Weimar Republic. He came from an affluent Jewish background, but like many such German Jews he fled Germany due to the Nazis. First to Czechoslovakia in 1933, then to Switzerland, and then France. In France he was interned along with Walter Benjamin. He would later flee Marseille and work with Varian Fry to help other artists or intellectuals fleeing Nazism. From 1941, he lived in New York. In 1952, Sahl became an American citizen. He became known as one of the anti-fascist exiles and in the US translated Arthur Miller, Thornton Wilder, and Tennessee Williams into German. In 1989, he returned to Germany.

Walter Georg Alfred Hasenclever (8 July 1890 – 22 June 1940) was a German Jewish Expressionist poet and playwright. His works were banned when the Nazis came to power and he went into exile in France. There he was imprisoned as a "foreign enemy". He died in Les Milles (Camp des Milles) near Aix-en-Provence.
