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 from 1930 until Bohr's death in 1962.[3] Rosenfeld published in 1930 the first systematic Hamiltonian approach to Lagrangian models that possess a local gauge symmetry, which predates by two decades the work by Paul Dirac and Peter Bergmann.[4] 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.[5]
In 1933, Rosenfeld married 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.[6]
Awards and honors
editRosenfeld held chairs at multiple universities: Liège, Utrecht, Manchester, and Copenhagen.[2]
In 1949 Léon Rosenfeld was awarded the Francqui Prize for Exact Sciences.[2]
