Harper was also active in a number of
bar associations. Sponsored for membership in the
New York City Bar Association by
Francis E. Rivers, the Association's first African-American member, Harper served on a number of the organization's committees, including those on Federal Legislation, Civil Rights, Legal Education and Admission to the Bar, and the Executive Committee. He also served as chairman of the board of the Association's
pro bono initiative, Volunteers of Legal Service (VOLS). He served as the City Bar's first African-American president from 1990 to 1992, where he worked to increase ethnic and gender diversity within the Association's committees and governance. Harper was a member of a number of other bar associations, including the
Metropolitan Black Bar Association,
American Bar Association, and the
New York State Bar Association. From 2000 to 2005, Harper served as the first African-American member of the
Harvard Corporation, the highest governing body of
Harvard University. In 2005, he controversially resigned from the board in protest over the leadership and high salary of Harvard President
Lawrence Summers, releasing a statement saying “I have reached the judgment that I can no longer support the president, and therefore I have resigned from the Corporation.” Harper has served on the board of trustees of a number of prominent cultural and political organizations, including the
New York Public Library, the
Museum of the City of New York, and the New York
Urban League. He has also served as Chancellor of the
Episcopal Diocese of New York and as
Legal Adviser of the Department of State. Harper was elected to the
American Academy of Arts and Sciences in 1992 and the
American Philosophical Society in 2002. ==Law reform work==
