On a cold December day in 1932, Marlin Kemmerer, left, sent dignified congressmen stampeding for the exits by waving a loaded revolver. As Kemmerer stood in the House gallery demanding to make a speech in the Chamber, Representative and World War I veteran Melvin Maas stood below and persuaded him to drop the gun, while Representative Fiorello La Guardia rushed upstairs and tackled him. Somehow Kemmerer and Maas found time for a photo op before the former was carted off by police.
