Laurie Wallmark
Hedy Lamarr's Double Life

HEDY LAMARR'S DOUBLE LIFE Meet savvy scientist and inventor Hedy Lamarr, also known for her career as a glamorous international movie star. Dubbed "The Most Beautiful Woman in the World," Hedy actually preferred spending time creating inventions in her workshop to strutting down the red carpet. Hedy co-invented the technology know as frequency hopping, which turned out to be one of the most important scientific breakthroughs of the twentieth century! Today's cell phone, computers, and other electronic devices would be more vulnerable to hacking without the groundbreaking system discovered by a world-famous actress and gifted inventor.
