Biography: A native of Williamsport, Pennsylvania, Dart began his career making crayon portraits as advertisements for the National Crayon Company. In the mid-1890s, he moved to the Boston Herald and then on to the New York World, which deployed him to Cuba as a sketch artist. He later became art editor for The World, where he called on his experience as a free-lance cartoonist to create the comic The Explorigator. The 1908 strip - about children flying an airship around the world - was designed to compete with Little Nemo by Winsor McCay in the New York Herald. It was short-lived but was the springboard for Dart's later work for Life and Judge; his cartoons often featured futuristic scenarios.
