Martin Luther King Jr. (January 15, 1929 – April 4, 1968) was an American Baptist minister and activist who became the most visible spokesperson and leader in the Civil Rights Movement. He is best known for his role in the advancement of civil rights using the tactics of nonviolence and civil disobedience based on his Christian beliefs and inspired by the nonviolent activism of Mahatma Gandhi.

In 1948, he graduated from Morehouse with a B.A. in sociology and enrolled in Crozer Theological Seminary in Chester, Pennsylvania, from which he graduated with a B.Div. degree in 1951.

King began doctoral studies in systematic theology at Boston University and received his Ph.D. on June 5, 1955, with a dissertation on "A Comparison of the Conceptions of God in the Thinking of Paul Tillich and Henry Nelson Wieman".

Decades later, an academic inquiry in October 1991 concluded that portions of his dissertation had been plagiarized and he had acted improperly. However, "despite its finding, the committee said that 'no thought should be given to the revocation of Dr. King's doctoral degree,' an action that the panel said would serve no purpose." The committee also found that the dissertation still "makes an intelligent contribution to scholarship." A letter is now attached to the copy of King's dissertation held in the university library, noting that numerous passages were included without the appropriate quotations and citations of sources.
