Jewish emigrants from Nazi Germany to the United States

Ludwig Marcuse (February 8, 1894 in Berlin – August 2, 1971 in Bad Wiessee) was a German philosopher and writer of Jewish origin.
From 1933 to 1940 Marcuse lived in France, settling with other German exiles in Sanary-sur-Mer. From 1940 to 1950 he lived in Los Angeles. He returned to Germany at the end of his life.
In 1962, his non-fiction book Obscene: The history of an indignation was published. The work revolves around leading obscenity trials: Friedrich Schlegel's Lucinde (Jena, 1799), Gustave Flaubert's Madame Bovary (Paris, 1857), Arthur Schnitzler's Round Dance (Berlin, 1920), D. H. Lawrence's Lady Chatterley (London, 1960), and Henry Miller's Tropic of Cancer (Los Angeles, 1962). A chapter is also devoted to the crusade of Anthony Comstock and the New York Society for the Suppression of Vice.
Marcuse wrote non-fiction, mostly about the role of German literature in so far as that it was bound up with progressive and emancipatory philosophical, and political causes. These works include subjects like Heine, Börne, Georg Büchner, the development of the tragedy, Sigmund Freud, the philosophy of happiness, and several others.
His papers are held at the University of Southern California.Ludwig was not related to Herbert Marcuse (another exiled German intellectual of Jewish descent) although he did have a brother by the same name.

Erich Auerbach (November 9, 1892 – October 13, 1957) was a German philologist and comparative scholar and critic of literature. His best-known work is Mimesis: The Representation of Reality in Western Literature, a history of representation in Western literature from ancient to modern times frequently cited as a classic in the study of realism in literature. Along with Leo Spitzer, Auerbach is widely recognized as one of the foundational figures of comparative literature.

Eduard Magnus Mortier Heimann (11 July 1889 – 31 May 1967) was a German economist and social scientist who advocated ethical socialist programs in Germany in the 1920s and later in the United States. He was hostile to capitalism but thought it was possible to combine the advantages of a market economy with those of socialism through competing economic units governed by strong state controls.

Eric Gutkind (also Erich; 9 February 1877 – 26 August 1965) was a German Jewish philosopher.

Margarete Berent (July 9, 1887, in Berlin – June 23, 1965, in New York), also known as Margareth Berent or Grete Berent in the United States, was the first woman lawyer in Prussia. She was the co-founder of the Association of Women Jurists and Association of German Women Academicians. As a Jew, she suffered from persecution during the Nazi Regime and fled via Switzerland, Italy, and Chile to the United States, where she finally arrived in 1940. After studying American law, she opened her second own law firm, now in the US, in 1951.

Rudolf Schindler (1888–1968) was a German physician, who practiced medicine as a gastroenterologist. He is regarded widely as the "father of gastroscopy."He was born in Berlin. During the First World War he described numerous diseases involving the human digestive system. He wrote the illustrated textbook, Lehrbuch und Atlas der Gastroskopie (Textbook and Atlas of Gastroscopy).
Between 1928 and 1932 Schindler worked with the Berlin-based instrument-maker and technician, Georg Wolf, on the development of the first semi-flexible gastroscope, which allowed a greater range for examination, facilitating diagnosis and some treatments without abdominal surgery.
With the rise of the Nazi party he was arrested. Upon his release in 1934, he made his way to the United States of America. He settled in Chicago, Illinois, and practiced medicine there until 1943. He then relocated to Los Angeles, California, where he continued his work in gastroenterology until his retirement. His work included writing two more books in the field of gastroenterology, teaching students, and saving lives.
Schindler was married to Gabriele Winkler, who was an important contributor to his work and they had two children. After her death in 1964, he married Marie Aumüller Koch, a pianist by whom he was the natural father of two children, including actress and later doctor Marianne Koch, before he fled Germany in 1934. They moved to Munich, Germany where he died in 1968.

Martin Foss (1889–1968) was a German-born American philosopher, professor, and scholar.

Rudolf Schoenheimer (May 10, 1898 – September 11, 1941) was a German-American biochemist who developed the technique of isotope labelling/tagging of biomolecules, enabling detailed study of metabolism. This work revealed that all the constituents of an organism are in a constant state of chemical renewal.Born in Berlin, after graduating in medicine from the Friedrich Wilhelm University there, he learned further organic chemistry at the University of Leipzig and then studied biochemistry at the University of Freiburg where he rose to be Head of Physiological Chemistry.He spent the 1930-31 academic year at the University of Chicago.In 1933, following the rise of the Nazis to power he emigrated from Germany to the Columbia University to join the department of Biological Chemistry. Working with David Rittenberg, from the radiochemistry laboratory of Harold C. Urey and later together with Konrad Bloch, they used stable isotopes to tag foodstuffs and trace their metabolism within living things.He further established that cholesterol is a risk factor in atherosclerosis.He suffered from manic depression all of his life, which led to him in 1941 committing suicide using cyanide. He had been honoured with the request to give the Dunham Lecture at Harvard before his death. It was read for him following his death.

Fritz Heinrich Lewy (; January 28, 1885 – October 5, 1950), known in his later years as Frederic Henry Lewey, was a German-born American neurologist. He is best known for the discovery of Lewy bodies, which are a characteristic indicator of Parkinson's disease and dementia with Lewy bodies.Lewy was born to a Jewish family in Berlin, Germany, on January 28, 1885. He trained in Berlin and Zürich and graduated from Berlin in 1910. He worked in Alois Alzheimer's Munich laboratory and was contemporary with Hans Gerhard Creutzfeldt (1885–1964), Alfons Maria Jakob (1884–1931) and Ugo Cerletti (1877–1963). In 1933, he fled Nazi Germany and moved to the United States. Lewy died in Haverford, Pennsylvania, on October 5, 1950, aged 65.

Herbert Max Finlay Freundlich (28 January 1880 in Charlottenburg – 30 March 1941 in Minneapolis) was a German chemist.His father was of German Jewish descent, and his mother (née Finlay) was from Scotland. His younger brother was Erwin Finlay Freundlich (1885–1964).
He was a department head at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry (now the Fritz Haber Institute) from 1919 until 1933, when the racial policies of the Nazi party demanded the dismissal of non-Aryans from senior posts. In 1934 he became a foreign member of the Royal Netherlands Academy of Arts and Sciences.Emigrating to England, Freundlich accepted a guest professorship at University College London. Five years later, he accepted a professorship at the University of Minnesota. He died in Minneapolis two years later.
Freundlich's main works dealt with the coagulation and stability of colloidal solutions.
His most prominent student was Robert Havemann who became a well known colloid chemist of the German Democratic Republic.
His work is of continuing importance, with his 1907 paper "Über die Adsorption in Lösungen" (On adsorption in solutions) becoming highly cited at the beginning of the 21st century. This early paper was based on his habilitation thesis written in Leipzig under the guidance of Wilhelm Ostwald, and was heavily based on the work of Sten Lagergren.
