During the West German era, new departments were added to the university. In 1954 the School of Protestant Theology was added, and the School of Law separated from the School of Economic and Social Sciences. This growth was accompanied by significant construction in the late 1950s and early 1960s. The Auditorium and the Philosopher's Tower were inaugurated near the Von-Melle-Park, while the Botanical Institute and Botanical Garden were relocated to Flottbeck. The university grew from 12,600 students in 1960 to 19,200 in 1970.
