[7] He matriculated in 1949 at Princeton University as a graduate student with fellowship granted by the Atomic Energy Commission and in 1951 won the $1000 top prize in an essay contest sponsored by the Gravity Research Foundation.
[10] As a postdoc he spent the academic year 1952–1953 under the supervision of Werner Heisenberg at the Max Planck Institute for Physics (which at that time was located in Göttingen).
[11] His 1960 article Electron-nucleus hyperfine interactions in atoms was mentioned in Robert H. Romer's list of memorable papers published in the American Journal of Physics from the years 1933 to 1990.
[12] His sabbatical leaves included visiting positions at the CERN laboratory[13] in Geneva and the Max Planck Institutes in Munich and Stuttgart.
[3] As postdocs in 1956, Michael Tinkham and Rolf Eldridge Glover III[19] demonstrated[20] "the existence of a superconducting "energy gap" by showing that light below a certain frequency was transmitted much more readily through a superconducting film than through a normal metal film.
