An Album of Presidents and Their Children

Harry S. Truman
Margaret Truman, left, the only child of Harry and Bess, pursued a career as a singer during the period her father served as President. Later in life, she enjoyed a successful career as a writer of murder mysteries, historical works and biographies of her parents. In the 1952 photo above, she joins her father in Kalispell, Mont., where he had been invited to throw a ceremonial switch, marking the start-up of the Hungry Horse Dam.
