(1951) and an addition Burcky gymnasium (1971), a sports facility with a 2,000-seat auditorium; Mosiman Hall (1960), the music building; a four-story expansion to the library (1966); Marbeck Center (1968), a student union with dining facilities, book store and other student facilities; and Riley Court (1969), a five-building complex that now house administrative offices. There were plans for future expansion and growth, but the 1970s instead were a time of retrenchment and conflict. Enrollment peaked at 789 in 1969 but dropped below 700 by 1972 and below 600 by 1975. The college fell deep into debt and made significant cut-backs. Bluffton's sixth president, Ben Sprunger (1972–1977), proposed increasing enrollment by transforming Bluffton into an evangelical college. This proposal was resisted by faculty, leading to Sprunger's resignation. However, during Sprunger's term, the college managed to balance the budget, conduct a successful capital campaign and construct Shoker Science Center (1978). Enrollment at Bluffton was below 600 for most of the 1980s, but the college experienced another era of growth and expansion in the 1990s under presidents Elmer Neufeld (1978–1996) and Lee F. Snyder (1996–2006), the first female president at Bluffton or any other Mennonite college. By 1995, the enrollment surpassed 1,000 for the first time. The college built two new residence halls, Ramseyer Hall (1994) and Neufeld Hall (2003), to meet housing demand. Other building projects included Sauder Visual Arts Center (1991), which houses an art gallery and studios for painting, drawing, sculpture and other arts; Yoder Recital Hall (1994), a 300-seat, state-of-the-art performance facility; and Centennial Hall (2000), a new academic building. Another major addition was the Emery Sears Athletic Complex, which includes 2,600-seat Dwight Salzman Stadium (1993) plus a baseball diamond, all-weather track, and soccer field. In 1995, Bluffton began a masters program in education, the first of its graduate programs. In 2004, the college, which now had three graduate programs, became Bluffton University. In 2006, James Harder became Bluffton's ninth president. He was succeeded in 2018 by Jane Wood. Religious heritage Bluffton University was founded as Central Mennonite College by the General Conference Mennonite Church and became affiliated with Mennonite Church USA when it was created in 2002 by a merger between the GCMC and the Mennonite Church. It has been a member of the Council for Christian Colleges and Universities since 1991. The Mennonite church is an Anabaptist denomination committed to nonviolence, social justice, and voluntary service. However,
