The Marianna Brown Dietrich College of Humanities and Social Sciences (Dietrich College) is the liberal and professional studies college and the second-largest academic unit by enrollment (after the Carnegie Mellon College of Engineering) at Carnegie Mellon University in Pittsburgh, Pennsylvania, USA. The college emphasizes study through rigorous analysis and technology of the behaviors, institutions, and beliefs that constitute the human experience, describing itself as “not an ordinary liberal arts school.” The college was named for Marianna Brown Dietrich, the mother of philanthropist William S. Dietrich II, after his donation of $265 million to the university in 2011 – the largest single donation in Carnegie Mellon history. The Dietrich College offers more than 60 majors and minors through its academic departments and specialized degree programs. It is committed to a balance among humanistic, scientific, and professional orientations, and to an emphasis on integrating research experience into undergraduate education. The Dietrich College General Education Program combines required courses that teach key analytical skills with a wide range of elective courses to develop foundational skills essential to effective learning throughout the college career and beyond. About the Dietrich College The College of Humanities and Social Sciences admitted its first freshman class in 1969, following the announcement of the pending closure of the Margaret Morrison Carnegie College, although roots of the college can be traced to the Division of Applied Psychology, founded in 1915 and led by Walter Van Dyke Bingham and Walter Dill Scott as the first research-oriented department within Carnegie Mellon. The administrative offices of the Dietrich College are located in Baker Hall. Most of the classes offered by the Dietrich College are held in Baker Hall and Porter Hall, but some classes, particularly the smaller recitation classes, are held in various locations throughout the campus. All undergraduate students at Carnegie Mellon are required to take several Dietrich classes (at least two, but usually more) as part of their program's General Education requirements. Dietrich College's general education program has been called "the most creative general education program of any American university" by The New York Times. The founding Dean of the Dietrich College was Erwin Steinberg. Past deans include John Patrick Crecine, Stephen Fienberg, Joel A. Tarr, Peter Stearns, and John P. Lehoczky. The current Dean is Professor of Philosophy Richard Scheines, who began his term on July 1, 2014. In December 2014, the Andrew W. Mellon Foundation awarded the Dietrich College
