Catherine Brieger Stern (1894–1973) was a German psychologist and educator. Born under the name Käthe Brieger, she developed sets of mathematical manipulatives similar to Cuisenaire rods for children to use in building up their number sense and knowledge of arithmetic. Her book, Children Discover Arithmetic (1949) was used by others to work on the problems that children face when learning arithmetic.In 1938, she emigrated to the United States. From 1940 to 1943, she was a research assistant to Max Wertheimer at the New School for Social Research.

Ludwig Paul Koch (13 November 1881 – 4 May 1974) was a broadcaster and sound recordist. An expert on recording animal sounds, he played a significant part in increasing the British public's appreciation of wildlife.

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.
