He was important for the creation of modern large-scale [[particle accelerator]] concepts. His most notable discovery was his 1952 work with [[Milton S. Livingston]] and [[Hartland Snyder]] on the [[Strong focusing]] principle,<ref>{{Cite journal | last1 = Courant | first1 = E. D. | author-link1 = Ernest Courant| last2 = Livingston | first2 = M.
