Providence - Clair Leon Wyatt, 78, died on April 9, 2008, at Sunshine Terrace in Logan, from complications associated with Alzheimer's disease. He was born on February 16, 1930, in Logan, to William L. and Nona Goldsberry Wyatt. Clair graduated from Logan High School in 1948, and then served a mission for the Church of Jesus Christ of Latter-day Saints in the British Mission from 1950 to 1952. Clair married Carolyn Jensen in the Logan LDS Temple on March 18, 1955, and two months later graduated from Utah State University in Electrical Engineering. Following graduation he was commissioned as an officer in the United States Air Force, attended meteorology school at UCLA, and served as a weather forecaster at Elmendorf Air Force Base in Anchorage, Alaska. Following service in the Air Force, Clair was hired as the first employee in the newly formed Space Dynamics Laboratory at USU in 1959. He earned a MS and PhD in Electrical Engineering from USU where he spent his career as a professor of Electrical Engineering and senior scientist at Space Dynamics Laboratory. He started the calibration lab at USU and became a leading world expert in radiometric calibration. Clair published several books, dozens of articles and encyclopedia entries, and received awards for his work in research, teaching and advising students. Clair retired from USU in 1993, and served a second LDS mission with his wife Carolyn in the Western Australia Mission from 1993 to 1994. He then served in the Logan Utah Regional Family History Center from 1994 to 2005, concluding his service as the director of the center. He had a strong testimony of the Gospel of Jesus Christ, loved the scriptures, and served in numerous church positions including Bishop and scoutmaster. His favorite calling was scoutmaster-he loved the boys and the mountains. He was proud of his ancestors and spent years researching and documenting their lives. He loved his family and they were a priority to him. He took his children and grandchildren on backpacking and canoeing trips, jeep rides and hikes. His favorite places included Mt. Logan, the Windrivers, Canyonlands and Yellowstone National Parks. He was fully engaged in life and learning, from studying the stars and planets to collecting and polishing rocks, from hiking down desert canyons to sleeping in snow caves and from reading the Greek philosophers to modem adventure stories. He could build or fix anything. He answered to the call sign NV7B on a lifetime hobby of Ham Radio. He loved and respected his wife Carolyn and she loved and cared for him to the last minute of his life.
