Dr. Alexander Scott Gilmour, Jr., aged 91, of St. Cloud, Florida, passed away peacefully at home on January 20, 2023, with loved ones near him. Scott is survived by his beloved wife of 27 years, Sally; his children David (Tami), Allen (Lauren Baker), Paula (David Longdon), and Duane (Shelly); his stepsons Blake Walker and Graham Walker; grandchildren Allison, Stephanie, Anna, Julia and Alex; and great grandchildren Sophie, and Millie. Scott was preceded in death by his parents, Alexander and Frances, his brother, George, and his beloved wife of 38 years and mother of his children, Mildred in 1994.

Scott attended Cornell University, where he received his bachelor’s degree in Electrical Engineering. After serving in the Navy, Scott returned to Cornell and obtained his M.S.E.E. and Ph.D. in Electrical Engineering. After two years as manager of the Electronics Department of Sanders Associates, he was appointed Professor of Electrical and Computer Engineering at the State University of New York at Buffalo. Scott was instrumental in the design, development, and application of microwave tubes, including their use by NASA and the Strategic Defense Initiative. He was appointed as a Fellow of IEEE in recognition of these accomplishments.

After his retirement from SUNY Buffalo, he presented nearly 200 courses on microwave devices, attended by professionals from around the world, and from most branches of the U.S. Armed Services. He commercially published 4 textbooks on Microwave Tube technologies, which have been published in several languages. Scott’s last book was published at age 88, more than ten years after having been diagnosed with Parkinson’s. He received several awards, including the 2018 IEEE John R. Pierce Award for Excellence in Vacuum Electronics, which is awarded by a committee of his peers and is considered the lifetime achievement award in his field. Despite his formidable accomplishments, Scott remained incredibly humble.

Scott had a passion for building things and used that passion to extensively renovate his home in Buffalo, and on Silver Lake, as well as to design his home on Alligator Lake. He could fix anything and was happiest with a hammer in his hand. Scott delighted in spending time with his family, especially at Silver Lake in New York and at Alligator Lake in Florida. Scott’s battle with Parkinson’s Disease was long, and in his later years a difficult one, but he faced it with grace and dignity.

Scott’s family would especially like to thank Scott’s stepson, Blake, who provided exceptional care to Dad during his final three years. Blake’s love for Dad allowed him to remain with Sally in his home in Florida to the end. In lieu of a funeral service, donations may be made to The Parkinson’s Foundation (www.parkinson.org) or Institute of Electrical and Electronics Engineers (IEEE, give.ieeefoundation.org).
