Hedy Lamarr's patent
Patent # 2,292,387 for a "Secret Communication System," granted to actress Hedy Kiesler Markey. At the time it was filed, in 1941, Lamarr was married to Gene Markey, a Hollywood screenwriter. She felt that having her married name on the patent would give it more credibility. This system could have inspired the scientists and engineers who developed GPS.
