Robert Hofstadter (February 5, 1915 – November 17, 1990)[1] was an Americanphysicist. He was the joint winner of the 1961Nobel Prize in Physics (together withRudolf Mössbauer) "for his pioneering studies ofelectron scattering inatomic nuclei and for his consequent discoveries concerning the structure ofnucleons".[2][3]

Biography

[edit]

Hofstadter was born in New York City on February 5, 1915, toPolish Jewish immigrants Louis Hofstadter, a salesman, and Henrietta, née Koenigsberg.[4][5][6] He attended elementary and high schools in New York City and enteredCity College of New York, graduating with a B.S. degreemagna cum laude in 1935 at the age of 20, and was awarded the Kenyon Prize in Mathematics and Physics. He also received a Charles A. Coffin Foundation Fellowship from theGeneral Electric Company, which enabled him to attend graduate school atPrinceton University, where he earned his M.S. and Ph.D. degrees at the age of 23.[7] His doctoral dissertation was titled "Infra-red absorption by light and heavy formic and acetic acids."[8] He did his post-doctoral research at theUniversity of Pennsylvania and was an assistant professor at Princeton before joiningStanford University. Hofstadter taught at Stanford from 1950 to 1985.[9]

In 1942 he married Nancy Givan (1920–2007), a native ofBaltimore.[10] They had three children: Laura, Molly (who was disabled and not able to communicate),[11] andPulitzer Prize-winnerDouglas Hofstadter.[12]

Opus

[edit]

Thallium-activated sodium iodide gamma ray detector

[edit]

In 1948 Hofstadter filed a patent on this for the detection ofionizing radiation by this crystal.[13][14] Thesethallium-activated sodium iodide detectors are widely used for gamma ray detection to this day.

Coining of the fermi (unit) and 1961 Nobel Lecture

[edit]

Robert Hofstadter coined the termfermi, symbolfm,[15]in honor of the ItalianphysicistEnrico Fermi (1901–1954), one of the founders of nuclear physics, in Hofstadter's 1956 paper published in theReviews of Modern Physics journal, "Electron Scattering and Nuclear Structure".[16] The term is widely used by nuclear andparticle physicists. When Hofstadter was awarded the 1961 Nobel Prize in Physics, it subsequently appeared in the text of his 1961 Nobel Lecture, "The electron-scattering method and its application to the structure of nuclei and nucleons" (December 11, 1961).[3]

Compton Gamma Ray Observatory and EGRET Telescope

[edit]

In his last few years, Hofstadter became interested inastrophysics and applied his knowledge ofscintillators to the design of theEGRETgamma-ray telescope of theCompton Gamma Ray Observatory named for fellow Nobel Laureate in Physics (1927),Arthur Holly Compton.Stanford University's Department of Physics credits Hofstadter with being "one of the principal scientists who developed the Compton Observatory."[17]
