Thomas Craig Sangster

Dr. Thomas "Craig" Sangster, born February 25, 1959, in Dallas, Texas, passed away suddenly on April 12, 2025, in Ocala, Florida. A devoted husband, father, scientist, and friend, Craig's life was marked by intellectual brilliance, boisterous "dad" humor, and a deep love for both discovery and the outdoors. He earned a Bachelor of Science from Baylor University before continuing to Purdue University to complete both his Master's and PhD in Physics while proudly cheering "Boiler up!" It was at Purdue that he met the love of his life, Rhonda. Their marriage was filled with shared adventures and enduring love for over 41 years. Craig began his professional career at Lawrence Livermore National Laboratory before moving on to the University of Rochester, where he retired in 2023. Over the course of his distinguished career in physics, Craig authored or co-authored numerous scientific publications and consulted for the National Nuclear Security Administration and Department of Energy. His contributions to science were vast, leaving a legacy in the field. Beyond his professional achievements, Craig lived a life rich with personal passions. A devoted golfer, through and through, Craig could be found playing in any weather: sun, rain, or even snow. Whether practicing for hours on the putting green, sharing laughs at Texas BBQ Joint after a round with his Rochester golf buddies, or morning rounds with his beloved group of friends affectionately known as the "old farts" he never missed an opportunity to play a round. A gifted pianist, Craig poured emotion into every note he played. His home often resonated with the lively syncopations of ragtime and the delicate intricacies of Chopin's etudes. Music was not just a hobby but a source of deep personal expression and comfort. From an early age, Craig was captivated by flight. During college he was a co-pilot on the Baylor University airplane, ferrying staff, athletes and alumni around the country. He also enjoyed piloting remote-controlled aircraft around local parks. Craig also cherished time spent outdoors with his sons as a Scoutmaster for Boy Scout Troop 310 of Penfield, NY. Many weekends were devoted to camping trips in New York's ever-changing weather, a reflection of Craig's enduring love for his boys. He is survived by his beloved wife Rhonda; their sons Doug (Diane, wife) and Trevor (Emma, partner); his sister Cindy; and many cousins who will remember him fondly. Craig was predeceased by his mother Geraldine "Gerry" Farmer and father Thomas Murdock Sangster. A memorial service to honor Craig's life will be held at 6:00 PM on Thursday, April 17, 2025, at Roberts of Ocala West Chapel, located at 6241 SW State Rd 200, Ocala, Florida 34476.
