Richard Feynman (1918 to 1988) was an American theoretical physicist whose work reshaped how physicists describe the interaction of light and matter. He shared the 1965 Nobel Prize in Physics with Julian Schwinger and Shin'ichirō Tomonaga for quantum electrodynamics, the theory that governs how charged particles and photons behave. The pictorial shorthand he invented, now called Feynman diagrams, turned some of the most forbidding calculations in physics into lines and vertices that a student can follow.
He was also, by wide agreement, one of the great teachers of his century, and a public figure who never quite behaved like one. He cracked safes at Los Alamos, played the bongo drums, and dismantled the official account of a space shuttle failure on live television. The record of his life is unusually full because he wrote so much of it himself, in lectures, letters, and two volumes of anecdotes that sold far beyond any physics classroom.
Feynman was born on 11 May 1918 in the Queens borough of New York City to Lucille and Melville Feynman. His father encouraged him from an early age to question authority and to look past labels for the mechanism underneath, a habit that shaped his entire approach to science. As a boy he repaired radios and kept a home laboratory, and he taught himself advanced mathematics well ahead of his schooling.
He graduated from Far Rockaway High School and went on to the Massachusetts Institute of Technology, where he switched from mathematics to physics and, still an undergraduate, helped derive what is now known as the Hellmann-Feynman theorem. He completed his doctorate at Princeton University in 1942 under John Archibald Wheeler, with a thesis titled "The Principle of Least Action in Quantum Mechanics" that laid the groundwork for his path integral formulation. That same year he married Arline Greenbaum, his childhood sweetheart, who was already gravely ill with tuberculosis; she died in 1945.
At the age of 24 Feynman was recruited to the Manhattan Project and sent to Los Alamos, where he worked in Hans Bethe's theoretical division and became a group leader despite his youth. After the war he joined Cornell University in 1945, and in 1950 he moved to the California Institute of Technology, where he was later named Richard Chace Tolman Professor of Theoretical Physics and stayed for the rest of his career.
His central contribution was to quantum electrodynamics, the quantum theory of how light and charged particles interact. Working independently, Feynman, Schwinger, and Tomonaga each found a way to tame the infinities that had plagued the theory and to make it yield finite, testable predictions. Feynman's route was the most visual: his diagrams represent each way that particles can interact as a simple picture, and each picture corresponds to a term in the calculation. The method proved so useful that it spread far beyond QED into nearly every branch of particle physics. The three men shared the Nobel Prize in Physics in 1965 for the work.
Feynman's reach extended well past his own research. His introductory course at Caltech was published as The Feynman Lectures on Physics, assembled from lectures he gave between 1961 and 1963, and it remains in print and in use decades later. His memoirs, "Surely You're Joking, Mr. Feynman!" and "What Do You Care What Other People Think?", carried his skeptical, playful voice to readers who never took a physics class.
He also pointed toward fields that did not yet exist. His 1959 talk "There's Plenty of Room at the Bottom" is often cited as an early vision of nanotechnology, and his lectures in the early 1980s on simulating physics with computers helped seed the idea of quantum computing. In 1986 he served on the Rogers Commission investigating the Space Shuttle Challenger disaster, where he showed on camera that a rubber O-ring lost its resilience in ice water, a plain demonstration of the failure that had destroyed the shuttle. He died in Los Angeles on 15 February 1988.
Feynman is remembered as clearly as he is because he left so much in his own words: lectures, letters, and stories he told against himself as readily as for himself. Confinity keeps his story as one example of how a life stays legible when its owner records it honestly, contradictions and all.
