Eleanor (Ellen) Creathorne Clayton (b. Dublin, 15 February 1834; d. London, 19 July 1900) was a magazine cartoonist, illustrator and writer. She was the daughter of Benjamon Clayton III, a member of a well-established family of Dublin engravers. The family moved to London when she was seven. Her earliest writing and illustrations were published in Chat, a newspaper owned by her father, and later in Punchinello, a comic paper owned by her father and some friends, and Sala's London. As it was all but impossible at that time for a woman to attend art school, she educated herself by copying at the National Gallery and the British Museum.
