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. 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 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.
