Ernst Carl Gerlach Stueckelberg (February 1, 1905 – September 4, 1984) was a Swiss mathematician and physicist, regarded as one of the most eminent physicists of the 20th century. Despite making key advances in theoretical physics, including the exchange particle model of fundamental forces, causal S-matrix theory, and the renormalization group, his idiosyncratic style and publication in minor journals led to his work being unrecognized until the mid-1990s.
Born into a semi-aristocratic family in Basel in 1905, Stueckelberg's father was a lawyer, and his paternal grandfather a distinguished Swiss artist. A highly gifted school student, Stueckelberg initially began a physics degree at the University of Basel in 1923.
While still a student, Stueckelberg was invited by the distinguished quantum theorist Arnold Sommerfeld, to attend his lectures at the University of Munich. He went on to gain a Ph D on cathode physics in 1927. Later that year he went to Princeton University, becoming an assistant professor in 1930.
He returned to Switzerland in 1932, working first at the University of Basel before switching the following year to the University of Zurich. In 1934 he moved again to the University of Geneva, which together with the University of Lausanne became his principal bases for the rest of his career.
Stueckelberg's sojourn in Zurich led to contact with leading quantum theorists Wolfgang Pauli and Gregor Wentzel, which in turn led him to focus on the emerging theory of elementary particles.
