Timeline

Shared physics Nobel
Recognised with Julian Schwinger and Sin-Itiro Tomonaga.
A physicist trained through several institutions
Richard Phillips Feynman was born in New York in 1918. He studied at the Massachusetts Institute of Technology, graduating in 1939, and received his doctorate from Princeton in 1942. During the Second World War he worked at Los Alamos on the Manhattan Project. After the war, Cornell provided the setting for a renewed concentration on theoretical physics. These institutions mark different phases of his life: undergraduate training, doctoral research, military work and the development of a postwar scientific programme.
New ways to organise quantum calculations
Feynman’s 1948 space-time paper offered a formulation of non-relativistic quantum mechanics equivalent to the established theory. Instead of assigning a probability separately to each alternative and adding the results, it combined complex contributions before calculating a probability. His later quantum-electrodynamics work introduced the diagrammatic methods associated with his name. The diagrams became computational tools, not miniature photographs of particle events. In 1965 he shared the Nobel Prize in Physics with Julian Schwinger and Sin-Itiro Tomonaga, whose approaches also transformed quantum electrodynamics.
Caltech research and a collaborative set of lectures
Feynman moved to Caltech in 1950 and worked across particle physics, superfluid helium and other problems. His teaching became a separate part of his influence. The Feynman Lectures on Physics emerged with Robert Leighton and Matthew Sands; attributing the volumes only to a charismatic lecturer obscures the work of organising, recording and developing the course. Caltech’s author account also records his work with Murray Gell-Mann on weak interactions. His scientific and educational output thus contains several different collaborations, rather than one permanent research partnership.
A public role beyond the blackboard
Late in his life, Feynman served on the commission investigating the Challenger disaster. His demonstration of how cold affected an O-ring became a memorable example of bringing a testable physical question into public discussion. He died in Los Angeles on 15 February 1988. His reputation rests on both research and explanation, but they should not be collapsed into personality alone. Reading a technical paper beside the lectures reveals a recurring concern: choose a representation that helps a reader calculate or reason, then keep that representation distinct from the physical event itself.
