Biographical Narrative Vern Oliver Knudsen was born December 27, 1893 at Provo, Utah, the youngest child of Scandinavian immigrant parents. At Brigham Young University (1911-1915), he was influenced by Professor Harvey Fletcher to study physics. After graduating with a B.A. in physics, he fulfilled a missionary obligation for the Mormon Church. During World War I, he studied Finding Aid for the Vern Oliver LSC.1153 2 Knudsen Papers LSC.1153 parasitic earth currents in relation to transatlantic telegraph communications and in 1918, he joined Harvey Fletcher at Western Electric, which later became known as the Bell Telephone Laboratories, where he worked on the development of amplifiers and oscillators, increasing his knowledge of the emerging technology of vacuum tubes which Fletcher and his colleagues were using in studies in hearing. Knudsen began graduate studies at the University of Chicago as a student of A.A. Michelson in 1915. Knudsen's doctoral research applied the vacuum tube techniques to a study of the sensibility of the ear to small differences of intensity and frequency. Robert A. Millikan, Chairman of the Physics Department at Chicago, introduced him to Dr. George E. Schambaugh, a foremost otologist. Knudsen and Schambaugh together investigated the sensitivity of pathological ears to small differences in loudness and pitch, and ten cases of diplacusis, the condition in which the same tone is heard at a different pitch in each ear. This led to later investigations of normal and impaired hearing with Drs. Isaac H. Jones and Norman A. Watson. Receiving the Ph.D. in Physics magna cum laude in 1922, Knudsen turned down offers from the University of Chicago and the Bell Telephone Laboratories, to accept the position of Instructor at UCLA, or rather the University of California Southern Branch, as the campus near central Los Angeles was then known. Here began Knudsen's close professional and personal lifelong relationship with Leo P. Delsasso, at that time a sophomore student who served as assistant to the department chairman. Knudsen confronted the lack of research space and equipment, and conducted studies of architectural acoustics and of hearing impairments. He and Dr. Jones developed the audiometer to assist in their research. Acoustics became a major emphasis of the UCLA Physics Department, and a reverberation chamber was to be one of the department's major facilities when the university moved to the Westwood campus in 1929. The work done here resulted in major experimental and theoretical research programs throughout the world. Knudsen was consulted on the acoustics of hundreds of structures, eventually to include major radio and motion picture studios, the Hollywood Bowl, the Dorothy Chandler Pavilion, and Schoenberg Hall, as an indication of his local contribution, but also on a wider scope, to include the United Nations General Assembly Building in New York. His two textbooks on architectural acoustics have become standard references on the subject. In 1928 Knudsen joined with Professor F.R. Watson (father of Norman A. Watson), Wallace W. Waterfall (a former student of Professor Watson) and Dr. Harvey Fletcher (of the Bell Telephone Laboratories) in founding the Acoustical Society of America. Knudsen served as president of the Society (1933-1935) and was honored by it in many ways. When UCLA began offering advanced degrees, Knudsen was a prime mover and first Dean (1934-1958) of the Graduate Division. The offering of graduate degrees by public universities was an innovative idea at that time. Students who did doctoral research under Knudsen included Norman Watson, Edwin Fricke, Richard Bolt, Robert Leonard, Richard Frick, and Isadore Rudnick. Other students who came under Knudsen's influence were W.A. Munson, Robert Watson, Cyril Harris, John Munier, Ludwig Sepmeyer, Waldo Lyon, Walter Rosenblith, Harper North, Paul Veneklasen, and Dah You Maa. During World War II, Knudsen, on leave of absence from academic and research duties, helped to organize and served as first director, of what is now the Naval Undersea Research and Development Center at San Diego. With the aid of Leo Delsasso and excellent scientists and staff recruited in a minimum of time, much early research on the propagation of sonar signals was accomplished. Knudsen became Vice Chancellor of UCLA in 1956 and Chancellor in 1959, a position which he held one year before reaching the mandatory age of retirement. "Retirement" for Knudsen meant a renewal of his research and consulting activities, finally reversing the increasing administrative demands which he had regretted since first becoming dean. Also renewed were his concerns with many causes such as environmental quality and, above all, his campaign against noise pollution. In addition to the Acoustical Society, Knudsen participated in the American Association for the Advancement of Science, the American Physical Society, the Los Angeles Building and Safety Commission, the California Institute for Cancer Research, the Board of Directors of the Hollywood Bowl Association, and the Hope for Hearing Foundation. He received great satisfaction in seeing the new physics building at UCLA named in his honor. Dr. Knudsen died May 13, 1974, at the age of eighty. He was survived by his widow, three children, and two grandchildren.
