Blackett; then professor at the Academy of Sciences, Berlin (1952 – 1961), and at the Institut Henri Poincaré, Paris 1960 – 1977.
Pastori
Maria Pastori (1895 – 1975). After teaching at elementary school, she entered Scuola normale superiore di Pisa and graduated as number one. She continued teaching in middle school and in 1929 became regular assistant in mathematics at the University of Milano. With the exception of years at the University of Messina from 1934 to 1939, she spent her whole carrier at the university of Milano. Her contributions were mostly in tensor analysis and differential geometry but she also was interested in quantum mechanics and thermodynamics.
Podolanski
Julius Podolanski (1905 – 1955), born in Poland grew up in Germany (in what now is Thuringia) to where his parents had moved. He received his PhD at the university of Jena. After having been assistant there and then with W. Heisenberg in Leipzig, although a German citizen, due to his being of Jewish descent he could no longer work at a German university after 1933. Jobless at first, he then could join the publisher Akademische Verlagsgesellschaft, Leipzig and, when proofreading H. Kramers’ article on Grundlagen der Quantenmechanik, he discovered errors and suggested improvements. Thus he got into contact with the impressed author. In 1937 he wrote letters to M. Born, H. Kramers and E. Schrödinger and presented them a manuscript on a new theory aimed at “replacing Dirac’s theory of the electron.” It unfortunately yielded two further particles, one spinless, the other uncharged with spin 1/2. Kramers managed to get him a position as assistant at the University of Leiden. After hiding in Utrecht during the later years of the war, he afterwards obtained a position in Utrecht with L. Rosenfeld, and since 1948 joined him again in Manchester [517].
Schrödinger
Erwin Rudolf Josef Alexander Schrödinger (1887 – 1961), Austrian theoretical physicist. He was the creator of quantum wave mechanics with his famous “Schrödinger equation” suggested in 1926. Nobel prize in 1933. Professor at the Universities of Stuttgart, Breslau, Zürich, Berlin, Graz, and Wien. Professor at and director of the Dublin School of Theoretical Physics between 1940 and 1956.
Sciama
Dennis William S. Sciama (1926 – 1999) was a British physicist who had earned his PhD in 1953 at Cambridge University with Paul Dirac. He taught at Cornell, King’s College London, Harvard and the University of Texas at Austin, but mostly at Cambridge (1950s and 1960s) and the University of Oxford (1970s and early 1980s). In 1983, he became professor of Astrophysics at the International School of Advanced Studies (SISSA) in Trieste.
Soh
Hsin P. Soh (Shu Xingbei) (1905 – 1983), after an education at Chinese Universities, continued his physics and mathematics studies at the University of California in San Francisco, at Cambridge University (with Eddington), and then at the Massachusetts Institute of Technology (with D. J. Struik). He received the chair position in the Department of Mathematics of Jinan University (Shanghai) and became professor at Zhejiang University (Hangzhou). His most famous student is the Nobel Prize winner Tsung-Dao Lee. Soh was purged heavily as anti-revolutionary in 1958 and rehabilitated fully only in 1979.
Straus
Ernst Gabor Straus (1922 – 1983) had to leave his birthplace Munich in 1933 with his family. He obtained his doctorate in mathematics at Columbia University in New York (1948) with Albert Einstein as his second adviser. He became an assistant of Einstein at the Institute for Advanced Study from 1950 – 1953. He spent his later academic career at the University of California, Los Angeles.
Thiry
Yves (René) Thiry (1915-); studied physics in Strasbourg with A. Lichnerowicz, and since the early 1960s became professor for physics at the astrophysical institute of the University of Paris, then professor for celestial mechanics at the University Paris VI, and corresponding member of the Academy.
Tonnelat
Marie-Antoinette Tonnelat, née Baudot (1912 – 1980) first studied philosophy and then joined the group of theoretical physics around L. de Broglie at the Institut Henri Poincaré, in 1925. She wrote her PhD thesis with him on the “Theory of the photon in a Riemannian space” in 1939. The “second part” of the thesis was done under the supervision of Jean Perrin on “Artificial Radioactivity”. It seems that she received her degree only in 1941. Since 1956 she became Professeur à la Faculté des Sciences of the University of Paris (Sorbonne); in this faculty she thus joined her teacher L. de Broglie. Mme. Tonnelat held a diploma in the history of science and, since 1949 regularly taught courses in this field as well. She also created an interdisciplinary seminar on the History of Sciences. Among her publications in this field, a book on the history of the relativity principle is to be noted [645*]. In 1945 she received the prize “Pierson Perrin” and in 1970 the prize “Henri Poincaré” of the Academy of Sciences in Paris [418, 92*]. Tonnelat also published a volume of novellas.
