Enrollment increased rapidly during the postwar period. In 1950, the Engineering and Industries building (now Weil Hall) was built to accommodate the need for more space. At that time, Weil Hall housed the entire college. In the 1950s, the University of Florida began enrolling women, and in 1955, the first woman graduated from the college with a master's degree in chemical engineering. In 1957, nuclear engineering was established as a department, and in 1959, the university's 10,000-watt nuclear training reactor became Florida's first critical reactor.
