Obituary

Thrygve Meeker was born in 1929 in Pottstown, PA to the late: Thrygve H. and Mabel (MacIntire) Meeker. He was married to his loving wife Joan (Honce), for 61 years. In 1951 he received his B.S. degree in chemistry from Ursinus College and his M.S. and Ph.D. in physics and chemistry, in 1954 and 1956, from the University of Delaware. In 1955 he joined Bell Labs where he addressed many of the important practical issues in communications related ultrasonic technology. As a Manager he helped develop the most complex monolithic crystal filter ever put into manufacture and led the development of the SAW timing recovery filter for the transatlantic fiber cable. Dr. Meeker was a leader in revising the IEEE piezoelectricity standards and received the IEEE Centennial Medal, in 1984 for his lifetime professional support of ultrasonics. In 1985, he received the IEEE UFFC Sawyer Award “”For his contributions to the theory and design of piezoelectric quartz devices.” He had served as president of the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society in 1965-1966. He had published some of his technical contributions. A selection of his articles and patents are listed below. He also authored “Theory and Properties of Piezoelectric Resonators and Waves,” Chapter 2 of Volume 2, in Precision Frequency Control, Edited by Eduard A. Gerber and Arthur Ballato, Academic Press, Inc., 1985. Dr. Meeker was a member of the First Presbyterian Church of Allentown, Alpha Tau Omega Fraternity, the American Chemical Society and the American Physical Society. He was predeceased by his parents and siblings Marjorie Middeler, J. Theodore Meeker, and Lawrence A. Meeker. Survivors: Wife Joan, Children: Linda Young and husband David, Diane Bartels, Thrygve K. Meeker and wife Barbara. Grandchildren: Samuel Young and Benjamin Young. Siblings Maurice Meeker and Marilyn Jones.
