Julia Parsons, U.S. Navy Code Breaker During World War II, Dies at 104

Soon after her officer training in Washington, she was recruited to a classified code-breaking team. She kept her work secret for decades, even from her family.

Apparently there was a command that went out among German communications, that they needed to stop using dirty words for the codes, because young girls were doing the codebreaking on the other side...
...and they kept guessing the codes as a result.
