Donald Clendenning M.S., ’66 passed away on August 9, 2016, in Lake Oswego, Oregon. Donald Campbell Clendenning began his life on April 20, 1931 in Gananoque Ontario. During his one year battle with Cancer he approached each day with the same inner strength that had guided his life full of hope and confidence that bright days were ahead. Don had a very fulfilling life and will be greatly missed by all who were touched by his love. Don was preceded in death by his three older brothers: Kenneth, Leonard, and Gerald. He is survived by his wife of 62 years Carolyn King Clendenning, formerly of Orillia and Cochrane Ontario. His is also survived by his three children: Doug Clendenning (Janet) Atherton California, Patty Nelson (Jim) Phoenix Arizona, and Donna Kasabian (Ron) Lake Oswego Oregon. In addition there are 7 seven grandchildren who he cherished time with: Kelly and Patrick Clendenning; Christian, Nicholas and Peter Nelson; and Andrew and Katie Kasabian. Don graduated from Queens University in Kingston Ontario with a BS in Engineering Physics in 1954 and a Master’s Degree from University of Santa Clara in Electrical engineering in 1967. Don’s brothers and his wife Carolyn also graduated from Queens University. Don and family came to Willow Glen in 1961 where they lived for 50 years while he built his career with Lockheed Missiles and Space. During the 32 years at Lockheed he designed flight control systems for missiles followed by greater responsibility around managing teams of engineers in the guidance and control division. He was affectionately known as a Rocket Scientist who directed the development of missile systems capable of detecting, intercepting and destroying incoming ballistic missiles out of the atmosphere. These projects had names like HOE, ERIS and Thad and took him to various places like the Kwajalein Islands to participate in missile launches. Don had many interests but foremost was his love of family. Family was the priority. Throughout the years he would be at his kids events whether baseball, softball, or dance and when needed he would coach and or volunteer in whatever way possible. Other major interests were camping, skiing, tennis (he played doubles into his early 80s) hiking, Hockey games (sharks), reading, bird watching and education. Once retired, they enjoyed trips to Hawaii and frequent cruises around the world. Don will be remembered for many things but love of family and the priority it was in his life will never be far from our hearts.
