John Turner, founder and principal engineer of Turner Engineering, passed away in December 2025, leaving behind a legacy of technical excellence, generosity, and mentorship. John’s career spanned decades in which he led Turner Engineering to become a leading and respected firm in systems design and broadcast integration. His technical insight, calm leadership, and unwavering commitment to quality earned him the respect of colleagues and clients alike.
Beyond his professional accomplishments, John was a person whose curiosity and kindness enriched the lives of those around him. One memory that I personally cherish occurred during the 2019 transit of Mercury, when Mercury passed across the face of the Sun—an event visible from Earth only rarely and not again until 2032. While I was organizing a public viewing of that celestial event, John graciously lent me one of Turner Engineering’s streaming servers so that the transit could be broadcast live over the Internet. When I offered to pay his usual rental fee, John insisted it wasn’t necessary, waiving the charge entirely as a personal favor—a testament to his generosity and support for science.
While I cannot confirm the specifics, I have long believed that John may have played a role in the work surrounding the restoration of the Apollo 11 lunar landing footage, including projects such as those undertaken by Lowry Digital.
He is survived by his family, close friends, and the many colleagues he mentored over the years. Those who knew him will remember not only his professional contributions, but also the countless quiet ways he made their lives better.
