Sinclair Lewis, Arrowsmith, (1925)
At the age of sixteen Lawrence entered St. Olaf College, a small Lutheran school in Minnesota. He intended to study medicine. After a year he transferred to the University of South Dakota, where he shunned fraternities for his studies. A professor of electrical engineering convinced Lawrence that his interest in radio pointed toward physics instead of medicine. In 1922 after graduating with high honors, Lawrence joined Tuve for advanced study in physics at the University of Minnesota under professor W.F.G. Swann. Lawrence followed Swann to the University of Chicago and then to Yale, where he completed his Ph.D. in 1924. Lawrence's dissertation on the photoelectric effectthe emission of electrons from a body struck by lightwas relevant to the new quantum physics.

Many American scientists of Lawrence's generation matured with the help of a new system of postdoctoral fellowships, which encouraged research rather than teaching. The National Research Council, established during World War I by the National Academy of Sciences, started granting such fellowships in 1919 with funds from the Rockefeller Foundation. American physicists, especially theorists, often used the postdoctoral fellowships to study in Europe. They brought home from Göttingen, Copenhagen, and Munich the new theory of quantum mechanics and began to teach it to their own students. Others, especially experimentalists, did postdoctoral research without going abroad. Lawrence, taking advantage of the first-rate physicists and well-equipped facilities at Yale, used his fellowship to continue research on photoelectricity and to start work on how atoms of a gas struck by electrons are ionized (an ion is an atom that has more or less than its normal number of electrons).
Despite a seemingly boundless capacity for work, Lawrence found some time for a social life. He met and courted Mary Blumer, the eldest daughter of a Yale professor of medicine. Molly, as she was known, at first spurned his advances, but Lawrence was nothing if not persistent. He finally won her over and they married in May 1932. They would have two sons and four daughters.Lawrence approached physics with a practical, experimental bent that followed the advice of Swann, his graduate advisor: "Cut-and-try sometimes is more important than too prolonged theorizing." The American tradition of pragmatism, prominent in the writings of William James and John Dewey, saw the value of knowledge in action, not contemplation. Lawrence would also exhibit another American predilectionfascination with big machines. Visiting European scientists of the time noted "the technological extravaganzas that Americans like so much."
