CLARKSON, THOMAS, one of the most zealous labourers for the abolition of the slave-trade, to which object he devoted his life, was the son of a clergyman at Wisbeach, where he was born in 1760. He lived to witness the extinction of the British slave-trade in 1807, and the emancipation of the negroes in 1838. He died at Playford Hall, Suffolk, in 1846. See SLAVERY.
