Fritz London
Fritz Wolfgang London (born March 7, 1900 in Breslau , † March 30, 1954 in Durham , North Carolina , USA ) was a German-American physicist .
Life
Fritz London came from a wealthy, upper-class German-Jewish family. He studied in Bonn , Frankfurt am Main , Göttingen , Munich and Paris . In 1921 he received his doctorate in Munich. After a brief activity as a teacher, London continued his physics studies in Göttingen and Munich (1922-25), was Paul Peter Ewald's assistant at the Technical University of Stuttgart in 1926/27 and studied with Erwin Schrödinger in Zurich and Berlin . Fritz London completed his habilitation in Berlin in 1928. He gave his first lecture as a private lecturer at the Friedrich-Wilhelms-Universität in Berlin in the winter semester of 1928/29 on quantum mechanics, especially applications to multi-body problems and chemistry .
Together with Walter Heitler published London, 1927, the first quantum-mechanical treatment of a chemical bond, namely the bond in hydrogen - molecule ( valence bond theory , valence bond, VB theory). After the seizure of power in 1933 he was forced to emigrate and between 1933 and 1936 he worked at Oxford University with his brother Heinz London , who was also a physicist . In 1936 he moved to Paris as research director.
In 1939 London emigrated to the USA, where he became professor of theoretical chemistry at Duke University in Durham. In 1953 he received a professorship for physical chemistry . In 1941 he became a Fellow of the American Physical Society .
plant
Fritz London developed the theory of the chemical bond between homopolar molecules. It is seen as a milestone in modern chemistry . Together with his brother Heinz London, he developed a phenomenological interpretation of superconductivity , which, with the help of quantum mechanics, contributed to a better understanding of chemical observations. In the USA he mainly worked in the field of superfluidity . In 1939 the book La théorie de l'observation en mécanique quantique (51 pages, Paris, Hermann & Cie) appeared, which he had written with Edmond Bauer (1880–1963).
