He did early work in quantum electrodynamics that predates by two decades the work by Paul Dirac and Peter Bergmann.
Rosenfeld contributed to a wide range of physics fields, from statistical physics and quantum field theory to astrophysics.Along with Frederik Belinfante, he derived the Belinfante–Rosenfeld stress–energy tensor.
He also founded the journal Nuclear Physics and coined the term lepton.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.
