Most of the departments of the University of Oslo are located at Blindern; other, smaller campuses include
Sentrum (law),
Gaustad (medicine),
St. Hanshaugen (odontology) and
Tøyen (botany, zoology, geology and paleontology). The central building is the new
university library,
Georg Sverdrup's house. Other buildings of note are
Eilert Sundt's house, the social studies building; the
humanities buildings, named after
Sophus Bugge,
Henrik Wergeland,
Niels Treschow and
P. A. Munch; Frederikke, the welfare building; and
Niels Henrik Abel's house, for mathematical studies, the biology building, named after
Kristine Bonnevie, the first female professor at Oslo University. Though the construction of a university campus at Blindern was decided on as early as 1921, the first buildings were not ready for use before 1931. Only in 1960 was Upper Blindern, the area most associate with the university today, finished. UiO today has approximately 32,000 students. ==Etymology==
