She was born in Indianapolis, Indiana. Thornbrough's major scholarly contributions include several publications devoted to black history, such as The Negro in Indiana before 1900; Booker T. Washington; T. Thomas Fortune, Militant Journalist; Since Emancipation: A Short History of Indiana Negroes, 1863–1963; and Indiana Blacks in the Twentieth Century (published posthumously in 2000).
