I like Hedy Lamarr. Gorgeous (Her beauty speaks for itself), Audacious (Check out 'Ecstasy'), Intrepid (Even though she was Jewish, she hobnobbed with Germen generals for technical information), and Smart (Her early work on frequency hopping was instrumental in both cellular telephony and WiFi).
(Yes, I do know what the topic is. But I am of an age where the total package adds to the appeal, To me, smarts and personality add to the charm-RHL)
