Richard Phillips Feynman was born on May 11, 1918, in Queens, New York, the son of Melville Feynman, a uniform salesman with a passion for science, and Lucille, who gave her son the gift of a sense of humor that would become as celebrated as his physics. From the earliest age, Feynman's father trained him to think not in labels but in mechanism — not 'that's a bird' but 'that bird's behavior tells us something about how it processes information about its environment.' This fundamentally INTP education — learning the world as a system of interconnected mechanisms rather than a catalog of named things — would define Feynman's entire scientific approach.
Feynman completed his undergraduate work at MIT and his PhD at Princeton, where he worked under John Wheeler. During World War II, he was recruited to the Manhattan Project at Los Alamos, where his combination of extraordinary mathematical ability and irrepressible irreverence made him one of the most memorable figures in the project's history — he famously spent his spare time cracking safes containing classified documents, not for any purpose but for the pleasure of the puzzle. He joined Cornell after the war and then moved to Caltech, where he would spend the rest of his career developing quantum electrodynamics, which describes how light and matter interact at the quantum level.
In 1965, Feynman won the Nobel Prize in Physics for his work on quantum electrodynamics, a theory he developed partly through the visual shorthand of Feynman diagrams — spatial representations of particle interactions that transformed how physicists visualized and calculated quantum events. He almost didn't win: he seriously considered declining the prize because he loathed the ceremony and what he perceived as the prize's transformation of science from a shared human enterprise into a competitive status system. He accepted because he was told that declining would attract more publicity than accepting.
Feynman's public legacy is as much about his philosophy of learning and scientific integrity as about any specific discovery. His Feynman Lectures on Physics remain the most celebrated physics textbooks ever written, beloved by students who describe them as reading like a physicist thinking out loud. His investigation of the Challenger Space Shuttle disaster in 1986 demonstrated both his physical intuition (he figured out the O-ring problem with a glass of ice water during the official hearing) and his integrity: he refused to sign the commission's final report unless they included his dissent about NASA's culture of ignoring inconvenient evidence.
