William J. Tanski, 67, of Glastonbury, CT, died at Saint Francis Hospital and Medical Center (Hartford, CT) on June 2, 2008. He was born on July 26, 1940, in Morristown, NJ, and had lived in Glastonbury since 1985. Bill received his BS degree in Electrical Engineering from The Pennsylvania State University, and his MS and PhD degrees in Physics from Georgetown University in 1970 and 1971, respectively. After serving in the US Navy as a nuclear reactor engineer, he began his career at the Sperry Research Center, in Sudbury, MA, in 1974. His early research work involved acoustic signal processing, and the development of VHF, UHF, and L-Band SAW resonator structures for a variety of oscillator and filter applications. After leaving Sperry, Bill worked at the Schlumberger-Doll Research Center in Ridgefield, CT, where he was involved in the development of SAW based pressure sensors. In 1985 he joined the United Technologies Research Center (UTRC) in East Hartford, CT, where he was engaged in the development of acoustic charge transport (ACT) and hetero-junction acoustic charge transport (HACT) device structures for signal processing and filtering applications. At UTRC he also continued his efforts to develop low noise SAW-based frequency sources for military applications. In recognition of his pioneering contributions to the development of SAW resonators, he was named an IEEE Fellow in 1992, with the following citation: “For developments in surface acoustic wave resonator devices”. During his career Bill was an active UFFC member, serving as a member of the Technical Program Committee for the Ultrasonics Symposium from 1980 to 1986, and also served as the UFFC Membership Chair for a number of years. Bill was an author of numerous technical publications during his career, as well as an inventor on many issued US patents. At the time of his death, he was working as an engineer for the United Technologies Otis Elevator subsidiary in Farmington, CT. Bill is survived by his wife Mary, and five sons.
