Jay Norwood 'Ding' Darling (1887-1962) was an American cartoonist and conservationist. A two-time Pulitzer Prize winner for editorial cartooning, he worked for the Sioux City, Iowa Journal, Des Moines, Iowa Register, and the New York Tribune. He helped initiate the Federal Duck Stamp program and designed the first stamp. Although a Republican, in 1934 he was appointed by President Franklin D. Roosevelt to head the Bureau of Biological Survey (which later merged with the Bureau of Fisheries to become the U.S. Fish and Wildlife Service). He was founder and first president of the National Wildlife Federation. J.N. 'Ding' Darling National Wildlife Refuge in Sanibel, Florida is named for him.
