1918 – 1988
Richard Feynman (1918–1988) was an American theoretical physicist and Nobel laureate known for his contributions to quantum electrodynamics, path integral formulation of quantum mechanics, and his celebrated popularizations of science. Though primarily a physicist, his views on the nature of time, physical law, and the limits of knowledge carry philosophical weight.
Developed the path integral formulation of quantum mechanics
Co-developed quantum electrodynamics (QED), earning the 1965 Nobel Prize in Physics
Introduced Feynman diagrams as a tool for calculating particle interactions
Authored influential works on the philosophy of scientific method and epistemology
Delivered landmark public lectures on physics and the nature of physical law
