On this day in 1940, nuclear physicist Ernest Lawrence was awarded the 1939 Nobel Prize in physics at a ceremony in Berkeley, California. He did not attend the usual ceremony in Sweden because of World War II. Lawrence invented the cyclotron, a high-energy particle accelerator that enabled unprecedented studies of atomic nuclei. During the war he was involved with the Manhattan Project. Element 103, lawrencium, is named after him, as are the Lawrence Berkeley and Lawrence Livermore national laboratories in California.
