During his lifetime and career, "Ding" Darling was most widely known for his editorial cartoons, which appeared in nearly 150 newspapers nationwide and earned him two Pulitzer Prizes. All of his cartoons were created and illustrated before the introduction of T.V. and many before even radio. In those days newspapers were the primary source of information and commentary, and were published frequently on the front page, having enormous impact on public opinion.
Ding's passion was teaching the wise use of the world's natural resources and advocating for environmental awareness. He was skilled in speaking, articulate in writing, and devoted his talents to the higher cause of conservation education and to developing programs and institutions which would benefit wildlife.
