Early Life and Education
Harvey Fletcher was born on 11 September 1884 and raised in Provo, Utah. Brought up in the community of Latter Day Saints, he remained active in the church throughout his life. He received his early training at the Brigham Young University from which he was graduated in 1907. He taught there for a year and married Lorena Chipman before moving to Chicago to continue his studies.
At the University of Chicago, Fletcher worked with Robert A. Millikan in measuring the charge on an electron. This fundamental research contributed greatly to the field of electronics and to the development of the radio and television industry. Upon hearing Millikan complain that the water droplets evaporated too fast in his famous "oil drop experiment", Fletcher went to the local jewelry shop for oil, acquired a perfume atomizer, and helped bring the experiment to a successful conclusion. He graduated with the first summa cum laude Ph.D. ever awarded by the Physics Department at Chicago.
Brigham Young University
Having promised to join the faculty of his alma mater, Fletcher returned to the Brigham Young University in 1911 as Chairman of the Physics Department. He was the only faculty member to have a Ph.D. degree in those years. He taught there for five years, continuing his research, building the physics faculty, and inspiring many students who went on to establish national reputations on the faculties of UCLA, University of Utah and Brigham Young.
Western Electric/Bell Labs
By the mid-1920s, when the Bell Telephone Laboratories was formed, Fletcher’s research on acoustics had developed into a separate unit. The company named him director of acoustical research in 1928 and by 1935 he had been promoted to Director of all Physical Research. In the 1930s, he was the first to demonstrate stereophonic transmission and stereophonic recording. In 1939, while working with Leopold Stokowski, he presented a concert featuring a stereophonic recording of the Salt Lake Tabernacle Choir to a capacity crowd in New York City's Carnegie Hall. During the Second World War, he contributed to work on underwater sound detection and identification.
Return to Academia
At age 65, Fletcher retired from Bell Labs to take a professorship in electrical engineering at Columbia University, where he helped develop a department on acoustics. He left Columbia after three years, to return to Brigham Young University. Here he developed the engineering course and became Chairman of Engineering Science, which later developed into the university’s College of Physical and Engineering Sciences. He returned primarily to his research beginning in 1960, with a particular interest in musical tones. He became Professor Emeritus at age 82, but continued his work until his death in 1981.
Professional Organizations, Accomplishments and Honors
Fletcher published extensively on his speech and hearing findings. Over the course of his career, he published over fifty papers, acquired some two score of patents and published a book entitled Speech and Hearing which became a standard text.
Fletcher helped found the American Acoustical Society and became its first president. He was elected an honorary member of this Society, an honor which is shared by only one other man-Thomas A. Edison. He was president of the American Society for Hard of Hearing, an honorary member of the American Otological Society and an honorary member of the Audio Engineering Society. He was also a member of the National Hearing Division Committee of Medical Sciences. In 1924 he was awarded the Louis E. Levy Medal for physical measurements of audition by the Franklin Institute.
Fletcher was a longtime member of the American Physical Society, becoming increasingly active upon his move to New York, and achieving the Presidency in 1945. In 1935 he became a member of the National Academy of Sciences. In 1937 he was elected vice-president of the American Association for the Advancement of Science. He was a Fellow of the Institute of Electrical and Electronics Engineers, an honorary member of Sigma Pi Sigma and a member of Phi Beta Kappa and Sigma Xi. He was given the Progress Medal Award by the American Academy of Motion Pictures, in Hollywood. For eight years he acted as National Councilor for the Ohio State University Research Foundation. High honors have also been given by the United States Army and Navy, and by the President of the United States.
Fletcher received honorary degrees from Columbia University, Stevens Institute, Kenyon College, Case Institute of Technology, the University of Utah, and Brigham Young University.
Fletcher served his church as well as science, first as President (equivalent of pastor) of the New York Branch of the Latter Day Saints Church and later as President of the New York Stake (equivalent of dioceses), as a member of the non-paid clergy.
Fletcher was awarded the IEEE Founders Medal in 1967 "For his creative contributions to the science of physical acoustics, electrical engineering, and for his management skills in the operation of a leading research laboratory."
