Ding Darling wielded a mighty pen. He started out as a political cartoonist for the Sioux City Journal and moved on to the Des Moines Register and later to the New York Globe. Though he won two Pulitzer Prizes, it is his work in conservation that endures. Host Charity Nebbe talks with Sam Koltinsky, the producer of new documentary exploring the life and work of Ding Darling. Then, Darling's grandson, Christopher Koss, shares his childhood memories of growing up with the artist.
