Hedy Lamarr was one of the most famous actresses of the 1930s and 40s. But she also was a brilliant technology innovator who developed one of the key processes in wireless technology still used today. Lamarr passed away in 2000, before many of her accomplishments were widely known. She was buried in her native Austria, but with nothing to mark her life and achievements. Actress Susan Sarandon has long been aware of Lamarr’s work in technology, and helped fund a memorial dedicated to it. The memorial features 88 steel rods that represent the 88 frequencies that Lamarr worked with as part of her patented technology.
