As a young sailor John Newton was prone to drunkenness, profanity, and myriad forms of irresponsible behavior. He converted to Christianity in his mid-twenties yet accepted a position as captain of a slave ship, sometimes conducting Bible studies onboard. After leaving the slave trade he became a pre-eminent figure in the Anglican Church, well known for his sermons, letters, and over two hundred hymns, including the venerable ‘Amazing Grace.’ In later years he became a prominent figure in the British abolitionist movement and a powerful weapon in the fight that would end the slave trade and, ultimately, slavery itself in the British Empire.
