(1810–1875), British publisher and educator, born in Southampton, Hampshire. Raised as a Quaker, Clark continued his classical, geography, and science studies even when he joined his father's brush- and basket-making business at the age of thirteen. From 1836 to 1843 he was a partner in the publishers Dartons, for whom he wrote and edited Peter Parley's Annual to subsidize his studies at Magdalen Hall, Oxford, where he gained his degree in 1846. During this time he also wrote many books of instruction for children, including The Book of the United Kingdom, Written by Uncle John (1841), Reuben Rambles Travels in the Western Counties of England (1845), and The Child's Treasury of Knowledge and Amusement (1845). His later work was largely cartographic or religious. As vice- principal of St. Mark’s Training College for Schoolmasters, and then principal of the Training College in Battersea, he significantly improved the quality of teaching in national schools.
