Born on a day like today
A prominent German physicist, Born taught theoretical physics at the University of Göttingen from 1921 to 1933, until Nazi policies forced him—a person of Jewish descent—to flee to England, where he continued to teach at the university level. He made contributions to various branches of physics, including solid-state physics and optics, but his most important work was that related to quantum mechanics—work that earned him a Nobel Prize in Physics in 1954. Born was one of 11 signatories to what?
