His monumental contributions to American security are largely unknown to Americans today.
Seventy-six years ago on Dec. 7, 1941, the Imperial Japanese fleet surprise-attacked Pearl Harbor, Hawaii, the home port of the U.S. Pacific Fleet. Japanese carrier planes killed 2,403 Americans.
They sunk or submerged 19 ships (including eight battleships destroyed or disabled) and damaged or destroyed more than 300 planes. In an amazing feat of seamanship, the huge Japanese carrier fleet had steamed nearly 3,500 miles in midwinter high seas.
The armada had refueled more than 20 major ships while observing radio silence before arriving undetected about 220 miles from Hawaii.
