President Bok reached into his bag of tricks this week and pulled out two mildly surprising appointments as Masters for Adams and Dunster House.

James Vorenberg '48, professor of Law, was chosen to replace Roger Rosenblatt, assistant professor of English, who has resigned as Dunster House Master to become the director of the education division of the National Endowment for the Humanities.

Robert J. Kiely, associate dean of the Faculty for Undergraduate Education, will succeed William Liller '48, Wilson Professor of Applied Astronomy, as the Master of Adams House. Liller announced last month that he would not reassume his Master's duties when he returns in 1974 from a year on sabattical.

Neither student preference lists nor Administration sources had mentioned either of the appointees as likely candidates for the positions. Sources speculated last month that John Wormack Jr. '59, professor of History, might be selected to replace Liller.

Eighty Dunster House residents last month sent a letter to Bok requesting that he appoint Caroline W. Bynum '63, assistant professor of History, as the new Master. The Dunster House Committee prepared a list of 28 possible candidates for the position in January. The list did not include Vorenberg.

Kim Q. Matland '71, chairman of Dunster House Committee, said last week that house residents would have preferred the appointment of a person connected with the house.

He added, however, that students could not judge who would make the best Master because "they don't know the faculty in other parts of the University."

Bok appoints Masters with the assistance of Dean Whitlock.

Vorenberg, director of the Harvard Center for Criminal Justice, will be the second current Master who is not a member of the Faculty. Kenneth R. Andrews, master of Leverett House, is a professor of Business Administration.

Vorenberg said last week that his connections with the Law School and the Center for Criminal Justice may "provide some opportunity for House residents to get involved in that kind of activity."

Kiely, a professor of English, also said that he is interested in "putting the Mastership together" with his other job.

Both Kiely and Vorenberg said that they plan to spend time in the next few months talking to the students in their respective Houses.

Vorenberg served as an advisor on crime and drug policy for Senator George S. McGovern (D-S.D.) in the 1972 presidential campaign. He was director of the Office of Criminal Justice under Attorney General Robert F. Kennedy '48.

Kiely was appointed to his position as dean of the Faculty for Undergraduate Education early this Fall. He is the author of Robert Louis Stevenson and the Fiction of Adventure and The Romantic Novel in England.
