If you need any other inspiration today, take a gander at the tale of Hedy Lamarr, once dubbed “The Most Beautiful Woman in Films.” She was gorgeous in Ziegfeld Girl with Judy Garland Lana Turner, though most people would probably immediately recognize her for Cecil B. DeMille’s Samson and Delilah, wherein she wears a gown festooned with peacock feathers before Samson brings the temple tumbling down.

But Hedy was more than just beauty. With composer George Antheil, she developed spread spectrum and frequency hopping technology to defeat Axis jamming of Allied signals during World War II. The Navy didn’t actually adopt the technology until the ’60s (after Lamarr and Antheil’s patent had expired), but the principles of their work form an important part of our modern WiFi, Bluetooth and CDMA technology. So if you’re out and about, tweeting or surfing on your phone, today of all days, say “Thank you,” to Hedy Lamarr.

Hedy is also the subject of today’s Google Doodle, a reminder that we may know the image, but the real story is what lurks beneath.
