For years, Wauneta Seiberts family had no idea what she did during World War II.
There was a reason for that.
Steeped in secrecy, Seibert was with the Naval intelligence effort during the height of the war, from 1942 to 1945, working as a codebreaker in an underground bunker in Washington, D.C.
It was her charge to decipher countless spools of 36-millimeter film filled with coded messages from a number of countries, primarily Japan.
She was good at it, too.
She helped break one code that identified where a pair of Japanese battleships were preparing to ambush an Allied fleet in the Pacific Ocean.
