Biography

Physicist Richard Feynman won his scientific renown through the development of quantum electrodynamics, or QED, a theory describing the interaction of particles and atoms in radiation fields. As a part of this work he invented what came to be known as "Feynman Diagrams," visual representations of space-time particle interactions. For this work he was awarded the Nobel Prize in physics, together with J. Schwinger and S. I. Tomonaga, in 1965. Later in his life Feynman became a prominent public figure through his association with the investigation of the space shuttle Challenger explosion and the publication of two best-selling books of personal recollections.

Feynman was born in the borough of Queens in New York City on May 11, 1918. He grew up and attended high school in Far Rockaway, New York. In 1939, he received his BS degree in physics from the Massachusetts Institute of Technology. He then attended Princeton University as a Proctor Fellow from 1940 to 1942, where he began his investigation of quantum electrodynamics under the supervision of J. A. Wheeler. He was awarded his PhD in 1942 for his thesis on the least action principle.

While still at Princeton, Feynman was recruited for the atomic bomb project. He was transferred to Los Alamos in 1942, where he headed a team undertaking complicated calculations using very primitive computers. While at Los Alamos, Feynman became good friends with Hans Bethe, who at the end of the war secured a position for Feynman as an associate professor of physics at Cornell. Feynman remained at Cornell from 1945 to 1951. During this time he formalized his theory of quantum electrodynamics and began to publish his results. He also participated in the Shelter Island Conference of 1947, which helped to determine the course of American physics in the atomic age. At this conference he introduced his theory of QED to the leading American physicists.

In 1951, Feynman accepted an offer to become the Richard Chace Tolman Professor of Theoretical Physics at the California Institute of Technology, a position he filled until his death. While at Caltech Feynman continued his work at the leading edge of theoretical physics, making important contributions to the study of liquid helium, particle physics, and later quantum chromodynamics. He also began his distinguished career as a teacher and lecturer. In 1961 and 1962 he delivered to Caltech's freshmen the introductory lectures that were later published as The Feynman Lectures on Physics .

In 1986, Feynman was asked to serve on the Presidential Commission investigating the space shuttle Challenger accident. In a dramatic fashion, Feynman publicly demonstrated the inelasticity of the shuttle's O-rings at near freezing temperatures, a leading cause of the disaster. He also contributed an extended appendix to the Committee's report, highlighting the technical and administrative deficiencies of the National Aeronautics and Space Administration's space program.

Feynman's many interests outside of science, such as his fondness for codes and safecracking, his bongo drums, his theatrical appearances, his artwork, plus his experiments in out-of-body experiences, are well documented in his autobiographies, as well as in his papers at Caltech.

Feynman continued his scientific work and his lecturing activities up until his death on February 15, 1988, after a long battle with a rare form of cancer.
