Tate’s impressive achievements didn’t stop there. She become the first African-American woman to earn a PH.D. in government and international relations from Harvard University (then Radcliffe College).
As an author, Tate published seven books, which focused on the United States and the practice of disarmament or demilitarization. Because of Tate’s global influence and her role as a reporter, she was accused of being a spy, although those allegations were never confirmed.
Tate taught at Maryland’s Morgan State College (now Morgan State University) and was the Dean of Women at the school. She later became one of the first two women to join the faculty of Howard University’s Department of History and worked there until her retirement in 1977.
Tate, who never married or had children, died at the age of 91 in 1996.
