A leading figure in the feminist movement of women scientists in Germany in the first three decades of the twentieth century and an outstanding bacteriologist, Lydia Rabinowitsch-Kempner was a pioneer among women scientists, an exception among the first generation of women scientists in her combination of career and family.
Lydia Rabinowitsch was born on August 28, 1871 in Kovno (Lithuania), the youngest of nine children, to a wealthy Jewish family whose children all studied at university. Because of the laws that discriminated against women and Jews in her native land, she studied medicine at the University of Bern in Switzerland, receiving her doctoral degree there in 1894. With no possibility of becoming a scientist in Lithuania, Rabinowitsch sought and found work elsewhere, beginning as a guest at the Institute for Infectious Disease in Berlin under Robert Koch (1843–1910). From 1897 until 1898 she held the position of professor for bacteriology at the College for Medicine in Philadelphia in the USA. However, she gave up this position upon meeting the physician and bacteriologist Walter Kempner (1870–1920), whom she followed to Berlin, where they worked for a while under Koch. When they married in April 1898 at an International Congress in Madrid, even newspapers reported the event.
Lydia Rabinowitsch-Kempner and her husband were a classic couple in science, like the physicists Marie and Pierre Curie and the brain researchers Cécile and Oskar Vogt. They had three children: Robert (1899–1993), a lawyer and prosecutor for the USA in the Nuremberg trials; Nadeshda (1901–1932), a student of Anglo-American literature, who died of tuberculosis; and Walter (b. 1903), who became a scientist.
Lydia Rabinowitsch-Kempner was the second president of the Association to Support Women Students with Interest-Free Loans, which was established in 1900 by the physicist Elsa Neumann (1872–1902). She gave up this position only in the 1920s, when the inflation in Germany made it impossible to continue granting loans.
Lydia Rabinowitsch-Kempner became a specialist on tuberculosis, earning a reputation in Berlin after she discovered the dangers in milk production at one factory in the city. At first the discovery caused a scandal, but she was later highly honored for it. In 1912 Kaiser Wilhelm II decorated her with the title Professor, whereupon a second scandal occurred, as a result of attacks in antisemitic newspapers. Although Lydia Rabinowitsch-Kempner was both a world famous scientist and a professor, she was never able to attain an academic position at the University of Berlin. The Medical Faculty of the university rejected her request for “venia legendi” as lecturer in bacteriology. Several grants and other support enabled her to continue her scientific activities after leaving the Robert Koch Institute, while her husband worked as a physician. From 1918 until 1933 she held the position of director of the bacteriological laboratory at the Berlin Moabit Hospital. She was also editor of the Journal of Tuberculosis (Zeitschrift für Tuberkulose) until 1933–1934. A member of Berlin society and a highly respected woman scientist, Lydia Rabinowitsch-Kempner was one of the few women listed in the Handbook of German Society (Handbuch der Deutschen Gesellschaft. Berlin: 1930).
In 1933, with the rise of Nazism, Rabinowitsch-Kempner was deprived of all her positions and honors. Thanks to her friends in Philadelphia, both her sons emigrated to the USA. Lydia Rabinowitsch-Kempner died in Berlin on August 3, 1935 after a severe illness, but with the comfort of knowing that her sons were safe.
Long forgotten, Lydia Rabinowitsch-Kempner’s work was finally acknowledged after the publication of biographical and scientific works referring to her.
