Hedy Lamarr is said to have tipped the balance of WWII. Not only is she almost unbelievably beautiful, she was also exceedingly clever. She was the co-inventor of an early wireless form of communication; her invention allowed shortwave radio communications on the field. She gave the invention, for no compensation, to the US Government. the Germans did not yet have this capability. Hooray for Hollywood leading lady Hedy Lamarr.
