many drawings Osborn produced for Navy manuals; estimates range from 2,000 to 40,000. Osborn illustrated an estimated 2,000 educational posters for Navy pilots between 1942 and the end of the war, some of which appeared in the New York Times and Life magazine. For a while, "dilbert" became a synonym for "blunder" for Navy pilots. In 1943, Dilbert was played by actor Huntz Hall in a US Navy training film Don't Kill your Friends. Grampaw Pettibone During the Second World War Osborn also drew cartoons of an experienced but somewhat curmudgeonly old Navy pilot, Grampaw Pettibone. Known as the "Sage of Safety", this long-bearded ancient was created in 1943 to educate Navy pilots in safety following a series of avoidable flying mishaps. Osborn illustrated the feature in Naval Aviation News for over 51 years, from 1943 until 1994, when artist Ted Wilbur took over. Postwar career After Osborn's stint in the Navy ended in 1946, he wrote a book called War is No Damn Good!, including a nightmarish skull-like depiction of an atomic bomb's mushroom cloud drawn only two weeks after Hiroshima, which prompted critic Steve Heller to call it "the first antiwar book of the nuclear age." The title alluded to cartoonist William Steig's caption, "People are no damn good." Osborn later produced political cartoons, ridiculing Senator Joseph McCarthy, and a number of presidents, from Lyndon Baines Johnson through Ronald Reagan. His cartoons for magazines were frequently published in The New Republic, and also appeared in Fortune, Harper's, Life, Look, Esquire, and House & Garden. He was a political activist for a number of causes, including nuclear disarmament. Critical reception According to Osborn's New York Times obituary, over his 50-year career, Osborn's sardonic and often savage drawings in books and magazines have arrested readers with their images of bloated power, violence and death. At the same time, he could be wittily ironic about society's pretensions, spoofing subjects like psychiatry, suburbanites and social climbing. Osborn characterized himself as "a drawer" whose figures "seemed to come right out of my subconscious." Garry Trudeau called him "one of the very few masters of illustrative cartooning." Robert Motherwell wrote that his drawings were "so alive that they seemed to writhe on the page with an uninhibited energy .... Osborn's art is a call to responsible action."; Motherwell was among those who compared Osborn's graphic work to that of Daumier, Goya, Saul Steinberg, as
