Code Girls: The Untold Story of the American Women Code Breakers of World War II

by Liza Mundy

Tiny Jo Palumbo, daughter of an Italian immigrant laborer, was the person who swore in newcomers, and the sight of her administering the grave secrecy oath had inspired one code breaker to write a lyrical poem in her honor. Unlike the Navy, Arlington Hall also had an African American code-breaking unit. This was not so much because the place was unusually liberal-minded, but rather because Eleanor Roosevelt—or somebody at the top—had declared that 12 to 15 percent of the Arlington Hall workforce should be black. It was poor recompense for the fact that many of Arlington’s black residents had been pushed out of their homes by the construction of the Pentagon and other military edifices, but work was welcome and this was better than nothing. Arlington Hall’s African American workers had to take segregated transport to get there, and many, even those who were college graduates, were given menial jobs as janitors and messengers. But there also was a special code-breaking unit whose existence was unknown to many of the white workers.
