Hibben's successor, Harold Willis Dodds would lead the university through the Great Depression, World War II, and the Korean Conflict. With the Great Depression, many students were forced to withdraw due to financial reasons. At the same time, Princeton's reputation in physics and mathematics surged as many European scientists left for the United States due to uneasy tension caused by Nazi Germany. In 1930, the Institute for Advanced Study was founded to provide a space for the influx of scientists, such as Albert Einstein. Many Princeton scientists would work on the Manhattan Project during the war, including the entire physics department. During World War II, Princeton offered an accelerated program for students to graduate early before entering the armed forces. Student enrollment fluctuated from month to month, and many faculty were forced to teach unfamiliar subjects. Still, Dodds maintained academic standards and would establish a program for servicemen, so they could resume their education once discharged.
