enter a permanent relationship with the federal government, they turned to industry and to private foundations, but with only limited success. The most reliable support for mathematics emerged from universities, where the funding could be justified as part of a larger program of institutional improvement. Oswald Veblen, a leading mathematician and chair of the department, took this approach as Princeton was in the process of transforming itself into a recognized research institution. Veblen's skill in securing university funding helped to make the Princeton mathematics department a center of mathematics research. His strategy helped to split the field, however, between 'pure' mathematicians in academic settings and 'applied' mathematicians whose interest in the practical applications of their work allowed them to find support in industry. 1960s and 1970s Princeton was hardly untouched by the Vietnam War. Students for a Democratic Society (SDS) had an active Princeton chapter, which organized protests against the Institute for Defense Analysis and staged a protest that came to be known as the "Hickel Heckle," in which several SDS members demanded that Interior Secretary Walter J. Hickel "Talk About the War!" Three students were suspended over the incident. In 1971, the Third World Center, now the Carl A. Fields Center, was founded to address the concerns of minority students to have a facility of their own making for academic, political and social functions. 1980s and 1990s In 1982, the residential college system was officially established under Goheen's successor William G. Bowen, who would serve until 1988. During his presidency, Princeton's endowment increased from $625 million to $2 billion, and a major fundraising drive known as "A Campaign for Princeton" was conducted. President Harold T. Shapiro would succeed Bowen and remain president until 2001. Shapiro would continue to increase the endowment, expand academic programs, raise student diversity, and oversaw the most renovations in Princeton's history. 2000 to present In 2001, Princeton elected its first female president, Shirley M. Tilghman. Before retiring in 2012, Tilghman expanded financial aid offerings and conducted several major construction projects. Princeton's 20th and current president Christopher Eisgruber was elected in 2013. In 2017, Princeton University unveiled a large-scale public history and digital humanities investigation into its historical involvement with slavery called the Princeton & Slavery Project. The project saw the publication of hundreds of primary sources, 80 scholarly essays, a scholarly conference, a series of short plays, and an art project. In April 2018, university
