1905–1984 (age 79)
Biography
Ernst Stueckelberg (1905-1984) was a theoretical physicist of international renown whose pioneering work on quantum field theory, particle interactions, and the renormalization group left an indelible mark on modern physics. His subtle insights into the S-matrix and gauge invariance helped shape the frameworks that generations of physicists rely on today.
At the University of Geneva he was a quiet but inspiring teacher, guiding students through thorny equations with patience and humility, and offering thoughts on ethical responsibility as readily as technical precision. His colleagues remember him as a generous collaborator who believed that the pursuit of knowledge must go hand in hand with respect for the human beings who pursue it.
