The Stanford University School of Humanities and Sciences is the heart of the undergraduate program and grants the majority of Stanford University's degrees. The School has 27 departments and 20 interdisciplinary degree-granting programs. The School was officially created in 1948, from the merger of the Schools of Biological Sciences, Humanities, Physical Sciences, and Social Sciences. Those schools date from the mid-1920s when the university first organized individual departments into schools.[1]
