Pulitzer Prize Recipient Twice. He received the Pulitzer Prize in the category of Editorial Cartooning in 1924 and again in 1943. He was known best as a political cartoonist. Experts estimate that J. N. "Ding" Darling drew 15,000 editorial cartoons chronicling the history, trends, thoughts, and politics of the United States for the first half of the twentieth century. As an editorial cartoonist, he held positions for the "Sioux City Journal" from 1900 to 1906, and subsequently worked for the "Des Moines Register" until his retirement 1949, and at the peak of his career, nearly 150 syndicated daily papers carried his cartoons. His first political cartoon, which depicted Teddy Roosevelt shooting holes in the policies of three-time presidential candidate, William Jennings Bryan, appeared in the "Sioux City Journal" on June 27, 1900. His first Pulitzer Prize, which was only the second ever awarded for editorial cartoons, came in 1924. His second Pulitzer was awarded in 1943 for a cartoon showing the White House and the United States Capitol buried in a sea of paperwork. An avid conservationist, Darling gained recognition in this field as the founder and first president of the National Wildlife Federation and was instrumental in the development of the Cooperative Fish & Wildlife Research Unit Program and the Federal Duck Stamp program. He designed the first Federal Duck Stamp in 1934. Darling is credited with starting the national wildlife refuge system during United States President Franklin Delano Roosevelt's administration, when Darling became head of the U.S. Biological Survey, which evolved into the U.S. Fish and Wildlife Service. Serving 20 months in 1934 and 1935, Darling obtained $20 million for wildlife projects and bought 4-1/2 million acres for refuges. As a winter resident of Florida, he helped to establish the Sanibel Wildlife Refuge in 1945, which was renamed in his honor in 1967. He attended college in Wisconsin and South Dakota. In 1906 Darling married Genevieve Pendleton, and the couple had two children, John and Mary.
