(1905–1981), English writer whose work includes a biography of his friend, the poet Walter de la Mare. An experienced educationist best known for writing poetry for young children, he was prolific, editing sixteen anthologies and writing fifteen collections of his own poems, of which Secret as Toads (1972) and The Singing Time (1980) are excellent examples. Clark is essentially a nature poet; his work is currently out of fashion and difficult to find in anthologies. He shares with Matthew Arnold the distinction of being both a recognized poet and a member of the Inspectorate for Education.
