Edwin Albert Link (July 26, 1904 – September 7, 1981) was a pioneer in aviation, underwater archaeology, and submersibles. He is best known for inventing the flight simulator, commercialized in 1929, called the "Blue Box" or "Link Trainer", which started a now multi-billion-dollar industry. In total, he obtained more than 27 patents for aeronautics, navigation and oceanographic equipment.
