Robert Hofstadter Robert Hofstadter was born in 1915 in New York City. With findings drawn from his research on a particle accelerator, this physicist shed light on atomic structure and helped create an identifying order for subatomic particles. He also correctly predicted the existence of hte omega-meson and rho-meson. These feats, coupled with his studies of controlled nuclear fission, earned a Nobel Prize for Physics in 1961.

Robert Hofstadter Robert Hofstadter American scientist who was a joint recipient of the Nobel Prize for Physics in 1961 for his investigations of protons and neutrons, which revealed the hitherto unknown structure of these particles. He shared the prize with Rudolf Ludwig Mossbauer of Germany. Hofstadter was educated at Princeton University, where he earned a Ph.D. in 1938. As a physicist at the National Bureau of Standards during World War II, he was instrumental in developing the proximity fuse, which was used to detonate anti-aircraft and other artillery shells. He joined the faculty of Princeton in 1946, where his principal scientific work dealt with the study of infrared rays, photoconductivity, and crystal and scintillation counters. Hofstadter taught at Stanford University from 1950 to 1985. At Stanford he used a linear electron accelerator to measure and explore the constituents of atomic nuclei. At the time, protons, neutrons, and electrons were all thought to be structureless particles; Hofstadter discovered that protons and neutrons have a definite size and form. He was able to determine the precise size of the proton and neutron and provide the first reasonably consistent picture of the structure of the atomic nucleus. Hofstadter found that both the proton and neutron have a central, positively charged core surrounded by a double cloud of pi-mesons. Both clouds are positively charged in the proton, but in the neutron the inner cloud is negatively charged, thus giving a net zero charge for the entire particle.

Robert Hofstadter , Professor of Physics at Stanford University , was born in New York, N.Y., of parents Louis Hofstadter and Henrietta Koenigsberg, on February 5, 1915. Hofstadter attended elementary and high schools in New York City, and was graduated in 1935 from the College of the City of New York with the B.S. degree, magna cum laude On graduation from college Hofstadter received the Kenyon Prize in Mathematics and Physics, and a little later the Coffin Fellowship, awarded by the General Electric Company. He went to graduate school at Princeton University where he studied physics from 1935 - 1938, and received both the M.A. and Ph.D. degrees in 1938 from that institution. His Ph.D. work was concerned with infrared spectra of simple organic molecules, and in particular, with the partial elucidation of the structure of the now well-known "hydrogen bond". In 1938 - 1939 he was awarded a Procter Fellowship at Princeton University for postdoctoral work, at which time he began a study of photoconductivity in willemite crystals. This work led to the discovery, with R. Herman, of the warm-up dark currents which demonstrated the existence of trapping states in crystals. In 1939 Hofstadter received the Harrison Fellowship at the University of Pennsylvania where he helped to construct a large Van de Graaff machine for nuclear research. At Pennsylvania he first met L. I. Schiff, who has been a friend and colleague for many years.

The Scientist 5[1]:0, Jan. 07, 1991 News Robert Hofstadter By None Nobel laureate Robert Hofstadter, 75, died November 17 at his home in Stanford, Calif., after a long bout with heart disease. Hofstadter's early investigations, in which he measured the size of the neutron and proton in the nuclei of atoms, won him the Nobel Prize in physics in 1961. Hofstadter was one of the driving forces behind the creation of the Stanford Linear Accelerator. He also made substantial contributions to gamma ray spectroscopy, leading to the use of radioactive tracers to locate tumors and other disorders. Hofstadter earned his B.S. in 1935 at the City College of New York, and earned his Ph.D. in physics in 1938 at Princeton University. During World War II, following postdoctoral work at the University of Pennsylvania, he worked as a physicist at the National Bureau of Standards, where he helped develop the proximity fuse, an antiaircraft weapon. In 1950, Hofstadter joined the faculty of Stanford University, where he taught until 1985, when he retired as Max H. Stein Professor Emeritus of Physics. He directed Stanford's High Energy Physics Laboratory from 1967 to 1974. Hofstadter was known for his teaching as well as his research. He taught courses ranging from the introductory to the graduate level, including a nonmathematical physics course known as "Physics for Poets." The Scientist 5[1]:0, Jan. 07, 1991

BIOGRAPHICAL MEMOIRS National Academy of Sciences Robert Hofstadter By Jerome I. Friedman and William A. Little R OBERT HOFSTADTER WAS BORN in New York City, educated on the East Coast, but spent most of his academic career at Stanford University. He is best known for his work on determining the distribution of charge and magnetic moment in the nuclei of atoms and of the nucleons themselves, for which he was awarded a Nobel Prize in 1961. He extended the work done in the early part of the twentieth century by Ernest Rutherford, who had shown that atoms were composite, containing electrons and a nucleus many thousands of times smaller than the atom. Rutherford discovered this by scattering alpha particles from thin metal foils of the elements and measuring the number of particles scattered as a function of the angle. The surprisingly large number of particles that were scattered through large angles could only be explained by collisions with a heavy, very small, perhaps point-like, positively charged object, which he called the nucleus. Some 40 years later Hofstadter determined the internal structure of such nuclei by scattering high-energy electrons from thin targets and measuring the distribution of the number of these electrons as a function of angle. In these experiments he built on earlier work by others on electron-electron scattering from atoms and electron-nuclear scattering by Hanson, Lyman, and Scott at Illinois done at lower energies in 1951. Hofstadter showed that the nuclei had internal structure extending over a small but measurable distance and that the heavier nuclei had a relatively uniform density within a thin surface skin. The Nobel committee considered this to be the first "reasonably consistent" picture of the structure of the nucleus.
