Like President Park, Katharine E. McBride earned her undergraduate and graduate degrees from Bryn Mawr and brought to the presidency her experience as dean of Radcliffe College. She was a trained neurologist who taught both education and psychology. McBride led the College through a significant period of expansion — in the numbers of graduate and undergraduate students, in the number of scholarships and fellowships, and in the size and range of the curriculum. She oversaw the opening of the Child Study Institute and the creation of a lab nursery school. In the 1960s, she supervised new additions to the Park Science Center and the construction of the Marriam Coffin Canady Library as well as Erdman and Haffner residential halls. A strong advocate for academic and individual freedom, McBride led the College in its repudiation of McCarthy era loyalty oaths and Vietnam era mandated reporting of student protests. Her love of research in aphasia and adult intelligence informed and enriched her administration, and from her research she internalized what she called "an inclination to ask about every event or kind of behavior, 'What can we learn from this?'"
