Dr. Martha B. Lucas Pate (November 27, 1912 - May 16, 1983) was a Kentucky-born administrator of colleges and organizations dedicated to international affairs, education, humanitarian aid, and religion. She was best known for her tenure as the fourth president of Sweet Briar College from 1946 to 1950. After the Board of the college refused to integrate the school in 1949, she left to become active in the United Negro College Fund, the Foreign Policy Association, the Council on Religion and International Affairs, the Fund for Theological Education, the Institute for International Education, the Fund for Peace, and the New York Medical College, to name a few. She spent the last few years of her life lobbying against nuclear weapons.
