Robert Hofstadter and his family move to Stanford where he becomes Associated Professor of Physics at Stanford University. In the course of his studies he confutes the common thinking that protons, neutrons, and electrons are structureless particles. Hofstadter finds a way to determine the size and form of the proton and neutron and how they're charged in their core and surrounding. He teaches at Stanford University until 1985.

At the age of 75, Robert Hofstadter dies to due a heart attack at his home in Stanford.

Robert Hofstadter joins the faculty of Princeton University where he continues his former research on photoconductivity. Furthermore his work deals with infrared rays and crystal and scintillation counters.

Robert Hofstadter earns his PhD in 1938, the same year as his M.S. His dissertation is about the resonance-absorption of gamma radiation by atomic nucleotides.

Along with Rudolf Mössbauer, Robert Hofstadter receives the Nobel Prize for Physcis in 1961 for his investigations of the revelation of the unknown structure of protons and neutrons.
