In the early 1900s Westinghouse Electric employed an outstanding group of research engineers, including Phillips Thomas, who worked for the company for more than 35 years. In the early 1920s Thomas invented an "ultra-audible" microphone that enabled "scientists to hear sounds inaudible to the naked ear." He would later work on radio signal-controlled electric circuitry, and a vortex gun designed to eliminate smoke from factories by shooting it in vortex rings high into the atmosphere. After World War II, Thomas believed that the answer to mental telepathy might be found in the unexplored frequency band between ultra-short radar waves and the longest waves of light.
