Léon Rosenfeld

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

Léon Rosenfeld (1963)

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 PhD from a European university. They had a daughter, Andrée Rosenfeld (1934–2008) and a son, Jean Rosenfeld.[5]

Awards and honors

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]
