He’s a lawyer in Washington D.C. He’s been a broadcaster, an ad-agency owner, and wrote a book on radio announcing. But fans of Adrian Cronauer still know him best as the real soldier behind Robin Williams’ demented radio personality in the film “Good Morning Vietnam.” Cronauer was in Des Moines last (Friday) night to address the midwinter conference of the Iowa American Legion. He worked in broadcasting until the mid-80s, then became a lawyer. Cronauer says the last three years and four months he’s been a Special Assistant to the Director of the Prisoner of War and Missing Persons Office at the Pentagon, He says there still 88-thousand U.S. soldiers still missing from armed conflicts.Cronauer says 78-thousand of those are still missing from World War Two, about 8,100 from the Korean War, about 1,800 from the Vietnam war, 120 still missing from the era of the “Cold War,” and one unaccounted-for from each war in Iraq. He says about 120 people at his office in Washington work to keep the missing soldiers from being forgotten. He says they also try to keep people from being missing — by seeing that they have the best training and equipment “so we can find them before they get captured by the enemy.” Cronauer says he usually opens by answering questions about the film. After he talks about his work with POWs, he’ll close with a “few personal opinions” about patriotism and values for the next generation, he says.
