Léon Rosenfeld (1963)

Léon Rosenfeld (French: "[ʁɔzɛnfɛld]; 14 August 1904 in "Charleroi – 23 March 1974[1]) was a "Belgian "physicist and "Marxist.

Rosenfeld was born into a "secular "Jewish family. He was a polyglot who knew eight or nine languages and was fluent in at least five of them.[2]

Rosenfeld obtained a "PhD at the "University of Liège in 1926, and he was a close collaborator of the physicist "Niels Bohr. He did early work in quantum electrodynamics that predates by two decades the work by "Dirac and "Bergmann.[3] Rosenfeld contributed to a wide range of physics fields, from statistical physics and quantum field theory to astrophysics.[2] Along with "Frederik Belinfante, he derived the "Belinfante-Rosenfeld stress-energy tensor. He also founded the journal "Nuclear Physics and coined the term "lepton.[4]

In 1933, Rosenfeld married Dr. Yvonne Cambresier, who was one of the first women to obtain a Physics Ph.D from a European university. They had a daughter, Andrée Rosenfeld (1934–2008) and a son, Jean Rosenfeld.[5]

Awards and honors[edit]

Rosenfeld held chairs at multiple universities: Liège, "Utrecht, "Manchester, and "Copenhagen.[2]

In 1949 Léon Rosenfeld was awarded the "Francqui Prize for Exact Sciences.[2]
