faculty, and staff member strike, so the university could become an "institution against expansion of the war." Princeton's protests would taper off later that year, with The Daily Princetonian saying that, "Princeton 1970–71 was an emotionally burned out university." 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. In 2001, Princeton shifted the financial aid policy to a system that replaced all loans with grants. That same year, Princeton elected its first female president, Shirley M. Tilghman. Before retiring in 2012, Tilghman expanded financial aid offerings and conducted several major construction projects like the Lewis Center for the Arts and a sixth residential college. Tilghman also lead initiatives for more global programs, the creation of an office of sustainability, and investments into the sciences. 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 trustees announced that they would name two public spaces for James Collins Johnson and Betsey Stockton, enslaved people who lived and worked on Princeton's campus and whose stories were publicized by the project. In 2019, large-scale student activism again entered the mainstream concerning the school's implementation of federal Title IX policy relating to Campus sexual assault. The activism consisted of sit-ins in response to a student's disciplinary sentence. Coeducation The roots of coeducation at the university date back to the 19th century. Founded in 1887, the Evelyn College for Women in Princeton provided education to largely the daughters of professors and sisters of Princeton undergraduates. While no legal connection ever existed, many Princeton professors taught there and several Princeton administrations, like Francis Patton, were part of its board of trustees. It closed in 1897 following the death of its founder, Joshua McIlvaine.
