Dr. Rosemary A. Stevens, who was appointed Dean of the School of Arts and Sciences in 1991 by Sheldon Hackney, has resigned at the end of her first five-year term. In her letter to the SAS faculty, she said that a major factor in the timing of her decision to return to the faculty full-time was the request for a new, anniversary edition of her book, American Medicine and the Public Interest. Taking account of the relevant research, she wrote, as well as the stresses and strains in medicine and health since 1971, "is going to take an enormous amount of work, and I am anxious to begin." A highly productive scholar, Dr. Stevens came to the deanship as professor and chair of the Department of the History and Sociology of Science. She returns to that department, and Dr. Walter Wales of the physics department serves as interim dean until a permanent replacement can be chosen.In accepting Stevens' resignation, President Judith Rodin and Provost Stanley Chodorow expressed their regret at her departure together with their gratitude for her many accomplishments. They especially praised the Dean's advocacy of new instructional programs, graduate education, faculty development, and stronger SAS relationships with other schools and divisions. Dr. Stevens also presided over the successful conclusion of the School's major fund-raising drive in the Campaign for Penn, in which SAS met its unprecedented target of $250 million. "The University and we are deeply in your debt," said the President and the Provost. "You have our thanks, and thanks from the entire Penn community, for a job well done."
