His dissertation established the 'Chaffee gap' a method of producing continuous oscillations for long-distance telephone transmissions. He taught at Harvard; director of the Cruft Laboratory; co-director of the Lyman Laboratory of Physics; director of the Laboratories of Engineering, Science, and Applied Physics; research focused on electric oscillations, vacuum tubes, and optics, and he secured a number of patents for radio devices. During World War II he directed research leading to improvements in radar. He also did early work on weather control, using airplanes in 1924 to break up clouds by means of electrically charged grains of sand) <https://www.britannica.com/biography/Emory-Leon-Chaffee> Franklin Institute Awards online, July 11, 2018: E.L.
