American journalist and abolitionist, born at Newburyport, Mass.; in his native town he rose to be editor of the Herald at 19, and five years later became joint-editor of the Genius of Universal Emancipation; his vigorous denunciation of slavery involved him in a charge of libel and brought about his imprisonment, from which he was liberated by a friend paying his fine; at Boston, in 1831, he founded his celebrated Liberator , a paper in which he unweariedly, and in the face of violent threats, advocated his anti-slavery opinions till 1865, when the cause was won; he visited England on several occasions in support of emancipation, and in 1868 his great labours in the cause were recognised by a gift of 30,000 dollars from his friends (1804-1879).
