of what would become known as the Abelian Higgs mechanism. He also proposed the law of conservation of baryon number. The evolution parameter theory he presented in 1941 and 1942 is the basis for recent work in relativistic dynamics. In 1941 he proposed the interpretation of the positron as a positive energy electron traveling backward in time. In 1943 he came up with a renormalization program to attack the problems of infinities in quantum electrodynamics (QED), but his paper was rejected by the Physical Review. In 1952 he proved the principle of semi-detailed balance for kinetics without microscopic reversibility. In 1953 he and the mathematician André Petermann discovered the renormalization group. In 1976 he was awarded the Max Planck medal. His PhD students included Marcel Guénin. Stueckelberg is buried at the Cimetière des Rois (Cemetery of Kings), which is considered the Genevan Panthéon.
