  Robert Hofstadter Summary
When Hofstadter arrived at Stanford, he found that the university's linear accelerator (linac) was an excellent source of high-energy electrons that could be used to study the nucleus and its nucleons, the particles of which the nucleus is composed.
Hofstadter was born in New York City on February 5, 1915, the third of four children born to Louis (a salesman) and Henrietta Koenigsberg Hofstadter.
Robert Hofstadter (February 5, 1915 - November 17, 1990) was the winner of the 1961 Nobel Prize in Physics "for his pioneering studies of electron scattering in atomic nuclei and for his thereby achieved discoveries concerning the structure of the nucleons."

Bob Hofstadter's opposition to running SLAC as a national facility was not based on his wish to have the machine reserved for his personal use.

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.
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 Hofstadters had a long and happy marriage, punctuated with periods of great joy, but also, especially in the early years, with periods of worry and financial difficulty.

Robert Herman, a leading light in the wide world of science, died on Feb. 13, 1997, after a long, brave fight against cancer.
As a consequence of their studies in nucleosynthesis in the early expanding big bang universe, they made the first theoretical prediction, in 1948, of the existence of a residual homogeneous isotopic fl body radiation (microwave radiation) that pervades the universe, as a vestige of the initial big bang explosion.
In the late 1950s, he collaborated with Robert Hofstadter of Stanford University in developing a theoretical interpretation of experiments of scattering of high energy electrons on nucleons (neutrons and protons) conducted in the linear accelerator installation of Stanford.

Robert Hofstadter of Stanford University was awarded the 1961 Nobel prize in physics for discovering atomic nuclei structure.
Using a linear accelerator, he bombarded protons and neutrons with electrons at energies of 100-600 MeV, and found them to be composed of positively charged cores surrounded by shells of alternating negative and positive charge.
Since such photon shells must complete their loops at the speed of light in one wavelength, and we know the mass of each shell, and their wavelength is determined by their energy content in accord with Einstein's mass-energy equation, we can calculate the diameter that each shell would be if it were a circle.

 Nobelmen of 1961 -- Friday, Nov. 10, 1961 -- Page 1 -- TIME
Born in New York and educated at City College of New York and Princeton University, Hofstadter went west to Stanford in 1950 determined to attack the great mystery of the inner structure of matter.
Using a beam of high-energy electrons from Stanford's linear accelerator as a sort of microscope, he and a team of assistants proved that protons and neutrons, which form the bulk of matter, are dense at their centers, cloudlike outside and only one forty-thousandth of a billionth of an inch in diameter.
Later research taught Hofstadter that protons, which have positive charges, and neutrons, which are electrically neutral, are similar in structure.
