1938 and in 1954 was separated to become the University of New England. During the late 1960s, the University of Sydney was at the centre of rows to introduce courses on Marxism and feminism at the major Australian universities. At one stage, newspaper reporters descended on the university to cover brawls, demonstrations, secret memos and a walk-out by David Armstrong, a philosopher who held the Challis Chair of Philosophy from 1959 to 1991, after students at one of his lectures openly demanded a course on feminism. The philosophy department split over the issue into the Traditional and Modern Philosophy Department, headed by Armstrong and following a more traditional approach to philosophy, and the General Philosophy Department, which follows the French continental approach. The Builders Labourers Federation placed a ban on the university after two women tutors were not allowed to teach a course but the issue was quickly resolved internally. Under the terms of the Higher Education (Amalgamation) Act 1989 (NSW), the following bodies were incorporated into the university in 1990: Sydney branch of the Sydney Conservatorium of Music Cumberland College of Health Sciences Sydney College of the Arts of the Institute of the Arts Sydney Institute of Education of the Sydney College of Advanced Education (prior to 1981, named the Sydney Teachers College). Institute of Nursing Studies of the Sydney College of Advanced Education Guild Centre of the Sydney College of Advanced Education. The Orange Agricultural College (OAC) was originally transferred to the University of New England under the act, but then transferred to the University of Sydney in 1994, as part of the reforms to the University of New England undertaken by the University of New England Act 1993 and the Southern Cross University Act 1993. In January 2005, the University of Sydney transferred the OAC to Charles Sturt University. 2000s In 2001, the University of Sydney chancellor, Dame Leonie Kramer, was forced to resign by the university's governing body. In 2003, Nick Greiner, a former Premier of New South Wales, resigned from his position as chair of the university's Graduate School of Management because of academic protests against his simultaneous chairmanship of British American Tobacco (Australia). Subsequently, his wife, Kathryn Greiner, resigned in protest from the two positions she held at the university as chair of the Sydney Peace Foundation and a member of the executive council of the Research Institute for Asia and the Pacific.
