Sovern became Dean of the Law School in 1970 and was named Executive Vice President of Academic Affairs and Provost in 1979. He became President of Columbia University in 1980. While President, he quadrupled Columbia's endowment, recruited many prominent faculty and presided over the opening of the University's main undergraduate division, Columbia College, to women students.
