Inventor. Born in Provo, Utah, he was a physicist known as the "Father of stereophonic sound". In the 1930s, as Director of all Physical Research at Bell Telephone Laboratories, he with Wilden Munson formulated a graph that is now referred to as the Fletcher-Munson Loudness Curves, which correlates between sound intensity and loudness. At Carnegie Hall in 1940, he made a presentation with recorded stereo music from a three-channel system using sound on film with a frequency range from 30 Hz to 15,000 kHz and a volume range of 120 decibels. For his accomplishments, he has been awarded the Progress Medal Award by the American Academy of Motion Pictures in Hollywood. He has published 51 scientific papers, two books and has been awarded 19 patents.
