Julia Childs was in the OSS and I believe it was Italy where she was based.
Greta Garbo while not in the military was a mathematician and developed a math method that she tried to give to the government for use in cryptology. The government was not interested then nor ever was. Well after the war, the math method was used as a basis for the machine language used in early computers. As she had earlier given rights to the government, she was never recognized nor compensated for her efforts when it went commercial.
