Charles Henry Ross, was the creator of Ally Sloper, one of the earliest cartoons on record.
Ross was author of several penny dreadful (the British equivalent of America's "dime novels", precursors of the early 20th century pulp magazines).
Ross lacked the artistic skills to fully render his creation, so his wife, Emilie de Tessier (using the name Marie DuVal), inked it for him. Later, she took over the series completely.
1880s, Ross and DuVal left the character, selling him for a flat fee to Judy's publisher, Gilbert Dalziel.
