Lot of three signed photographs of American soldiers associated with the ignored early radar indications of the large numbers of incoming Japanese aircraft en route to Pearl Harbor shortly before their attack on December 7, 1941. Included is JOSEPH L. LOCKARD, a 6 x 4 in. photo showing him at a radio set. Lockard was one of two soldiers manning the brand-new radar station at a hilltop at Opana Point on the northern tip of Oahu. Seeing a massive incoming flight, he called in warnings, finally reaching a lieutenant. The lieutenant told him not to worry, as it was probably a flight of B-17 Flying Fortresses due in that morning from California. WITH: KERMIT A. TYLER (1913-2010), USAF pilot and later brigadier general, S.P. 2.75 x 4.5 in. b/w, a portrait in flight gear. It was Tyler, untrained at the time, who received Lockard's warning message and failed to act on it. WITH: RICHARD SCHIMMEL, another Army radar observer who was at the intercept center at Fort Shafter and discovered the warning message balled-up and in the trash, an S.P., 4 x 6 in. b/w, wartime pose. Three pieces.
