Codebreaker Helen Fairbank took the secrets from Bletchley Park to her grave when she died last month.
She spent the final 28 years of her life working at Traquair House near Innerleithen, Peeblesshire.
But the 90-year-old will be best remembered for her part in bringing down the Nazis, although she never revealed her exact role in Hut 6 – the department which cracked the Enigma and Lorenz code machines.
