This engraving shows the Reverend Richard Watson. Watson was one of the first outstanding Wesleyan Methodist theologians and had a keen interest in promoting foreign missions. He became President of Conference in 1826. Watson is perhaps best remembered for his publication 'Theological Institutes' (1831), in which he tried to bring John Wesley's theology into a coherent system.
