University of Chicago

During Sonnenschein's presidency at the University of Chicago which started on July 1, 1993, he increased the school's fund raising expectations, devoted many resources to the improvement of campus life and facilities, fortified the enrollment of the best students in the nation, and furthered a comprehensive plan to continue expanding the undergraduate College which had been started by the previous presidents of the school. Sonnenschein's Campus Master Plan (only the fourth in the 108 year history of the school) included the construction of the Gerald Ratner Athletics Center, building a new campus for the Graduate School of Business and increasing the University library's capacity. During this time, University of Chicago students took first place in 14 of 21 fields of study and second in six of the remaining seven fields of study at junior-level faculty hires in universities across states. Under Sonnenschein's leadership, the faculty made significant changes to the curriculum, including a reduction to the required number of "Core" courses in the College. Some changes also included more opportunities for students to learn foreign languages and study abroad. These moves had the effect of producing capital through tuition and expanding the school's network of alumni and benefactors, but were also controversial. They were criticized by students, alumni, and faculty, who regarded them as watering down the university's academic standards. In Sonnenschein's third year, the university raised $676 million dollars for the purposes of supporting student aid, facilities, and research at the end of the school's five year "Campaign for the Next Century". During Sonnenschein's tenure, the university's endowment increased from $1.2 billion to $2.9 billion, following the increased fund raising rate in the president's last five years.
