Nuclear Physicists in a New World. The Émigrés of the 1930s in America

Kernphysiker in einer neuen Welt: Die Emigranten der dreißiger Jahre in Amerika. - Unter der großen Anzahl derjenigen, die durch Nationalsozialismus zur Emigration gezwungen wurden und zwischen 1933 und 1941 in die Vereinigten Staaten von Amerika einwanderten, befanden sich auch mehr als hundert Physiker, und unter ihnen einige der genialsten Kernphysiker der Welt. Die Physik in Amerika hatte damals den Status einer voll ausgereiften Wissenschaft erreicht, und so kam es zu einem bedeutsamen und facettenreichen Zusammenwirken zwischen den emigrierten und den einheimischen Kernphysikern, zumal sie die verschiedenen Forschungsgebiete vertraten, die sich durch die Entdeckungen und Erfindungen des Jahres 1932 (Neutron, Deuterium, Positron, Cockcroft-Walton-Beschleuniger, Zyklotron) aufgetan hatten. Von besonderer Bedeutung Für die Konsolidierung und Entwicklung der gesamten Kernphysik war dabei die Veröffentlichung von drei Artikeln in den Reviews of Modern Physics von 1936 und 1937, bekannt als die ?Bethe-Bibel”?. Nach der Entdeckung der Kernspaltung von 1938 und dem Ausbruch des Krieges 1939 in Europa wirkte die Befürchtung, daß Hitler eine Atomwaffe erhalten könnte, als mächtige, Emigranten und Nicht-Emigranten gleichermaßen erfassende einigende Kraft unter den Atomphysikern in Amerika, und die meisten von ihnen stellten ihre Fähigkeiten in den Dienst der US-Regierung und arbeiteten am Manhatten-Projekt und an anderen militärischen Forschungsvorhaben mit. Bei Kriegsende waren die in den dreißiger Jahren emigrierten Kernphysiker wie so viele Flüchtlinge vor ihnen Amerikaner geworden, und keiner von ihnen kehrte in sein Geburtsland zurück. Among the large number of refugees from Nazism and Fascism entering the United States between 1933 and 1941 were more than 100 physicists, including some of the most gifted nuclear physicists in the world. By that time physics in America had come of age, and a remarkable and multifaceted symbiosis occurred between the émigré and native-born nuclear physicists as they pursued the many avenues of research opened up by the discoveries and inventions of 1932 (neutron, deuterium, positron, Cockcroft-Walton accelerator, cyclotron). Of particular importance for the consolidation and development of the entire field of nuclear physics was the publication in 1936–37 of the three articles in the Revieus of Modern Physics known as the ?Bethe Bible”?. With the discovery of nuclear fission in 1938 and the outbreak of war in Europe in 1939, the fear that a nuclear weapon might fall into Hitler's hands served as a powerful unifying force among nuclear physicists in Amerika, émigrés and non-émigrés alike, and most placed their talents in the service of the United States Government working on the Manhattan Project and other wartime research. By the end of the war, like so many refugees before them, the émigré nuclear physicists of the 1930s had become Americans, and not one of them returned to the country of his birth.     

Politisch motivierte Emigration deutscher Ärzte

In 1933 the nazis had immediately started to reorganize the health service and the medical profession on the basis of eugenics and efficiency. For everybody who had been engaged in the institutions of social medicine or social hygiene in the Weimar Republic the inhibition of medical practice, misery, distress, persecution, imprisonment or at the best emigration had been the consequence of it, for political and mostly also for racial reasons. But for these physicians who had to flee from Nazi-Germany the situation in the immigration countries had not been a good one in most of the cases. Therefore it is only possible to speak - if you neglect the special situation of the psychiatrists in the U.S.A. - in particular cases of transfer of medical science into the immigration countries from Germany. Most of the immigrants stayed after the war in their new homelands. The loss of these progressive aspects of social hygiene caused by the emigration of these physicians 1933 and afterwards from Germany can be noticed in this field of medicine and public health service in Western Germany until now.     

Emigrierte deutsche Historiker in den USA

German Refugee Historians in the United States. - After the Nazi seizure of power in 1933, some twenty historians left Germany. They had lost their academic positions for political and/or ?racial”? reasons. Most of them immigrated to the United States, and here they launched their second academic career. This intellectual immigration promoted the study of German and intellectual history and strengthened the development of comparative approaches in American historical scholarship. Many German refugee historians became interested in incorporating social science concepts into historical writing and thereby contributed to the advancement of a ?Social History of Ideas.”? Although some were originally skeptical of the democratic process, in emigration these historians absorbed and accepted the political value system of a democratic and liberal republic, a change that is reflected in their historical studies. Despite the fact that almost all refugee historians chose to stay in the United States, their books and guest professorships left their mark on the course of West German historiography.     

Österreichische Ärzteemigration 1934-1945 - Zwischen neuem Tätigkeitsgebiet und organisierten Rückkehrplänen

Information on emigrant doctors and university teachers of medicine from Austria is rather poor up to now. This article is a preliminary sketch to give a first impression of the problems, quantity and quality of the doctors' emigration. First, there is made a distinction between different groups of emigrants, who emigrated at different times owing to the political changes in Austria (civil war and ?Anschluß”?). Then the emigration prior to the political set-ups during the thirties is discussed. The assertion is made, that the reasons for emigrating during the twenties are very much the same than in later years. Hostility against Jews, socialists, democrats and foreigners made living and working conditions increasingly unbearable. Concerning the influence of emigrated scientists on science and learning in immigration countries some theoretical and clinical sub-specialties of medicine are examined, e.g. social medicine, internal medicine, pharmacology, orthopedic surgery and child psychiatry. Whereas in some cases the influence is minimal, e.g. social medicine, other disciplines have been influenced enormously, e.g. child psychiatry. Finally there follows a short examination of the organisations of Austrian doctors and medical scientists in the United States and Great Britain.
