George Bourne (1780–1845) was an American abolitionist and Presbyterian minister. Widely acknowledged as the first to publicly proclaim “immediate emancipation without compensation,” he worked indefatigably against slavery, causing William Lloyd Garrison to say of him, “Never has slavery had a more indomitable foe or freedom a truer friend.” Bourne was also a successful writer, and his The Book and Slavery Irreconcilable was a key ideological tract spurring Christian abolitionism. His other works include Napolean Bonaprte, and the now lost Thomas Jefferson and His Presidency. Bourne edited several periodicals, including the Christian Intelligencer, and the Baltimore Daily Gazette. He founded the Protestant Reformation Society, which later became the American Foreign Christian Union.
