Lombardi, and then took added duties as the flagship's interim chancellor after Michael V. Martin announced in May that he was leaving that job. The board says it will search for a new president to oversee all of the university's entities.
Jacques Barzun, historian, cultural critic, and author of dozens of popular and scholarly books, died on October 25. He was 104. Mr. Barzun received a B.A., M.A., and Ph.D. from Columbia University, where he then served as a professor, dean, and later provost. Mr. Barzun was an important critic of American universities, arguing in 1968 that their curricula had become an undisciplined "bazaar" of miscellaneous studies. But he was also a popularizer, believing that the achievements of the arts and scholarship should not be divorced from the wider American culture. Writing for a general audience, he said, was "a responsibility of scholars."
