James Joseph Reeb was an American Unitarian Universalist minister, pastor, and activist during the civil rights movement in Washington, D.C. and Boston, Massachusetts. While participating in the Selma to Montgomery marches actions in Selma, Alabama, in 1965, he was murdered by white segregationists, dying of head injuries in the hospital two days after being severely beaten. Three men were tried for Reeb's murder but were acquitted by an all-white jury. His murder remains officially unsolved.
