If you’ve ever been knocked around by PMS you know that hormones can be powerful stuff. But powerful enough to have defeated Hitler?

That was the plan: to put estrogen in the Nazi leader’s food and thus feminize him, making him “less aggressive and more like his docile younger sister Paula, who worked as a secretary,” says the Daily Mail, which, in their ever-delightful Daily-Mail way, call it “The allied plot to turn Herr Hitler into Her Hitler.”

The plan is divulged in a new book, “Technology, Science and the Race to Win World War II,” by Professor Brian Ford of Cardiff University, who says that Allied researchers were just beginning to see the power of sex hormones. The British were poised to carry out this sex-seasoning business; the estrogen, they thought, would have gotten past Hitler’s food tasters, whereas poison would not. Hormones would take awhile to go into effect and no one would be the wiser, at least until he decided the Nazi salutation should be changed to “Hey, girl!” and started asking if his uniform made him look fat.

Other potential plans included “dropping glue and poisonous snakes on Nazi troops and sneaking bombs into Germany “in tins of fruit,” Time reports.
