Sad to learn of Fred's passing. We worked together at Itek in the early 60s and crossed paths when he worked at Pacific Optical decades later. I always enjoyed his British (almost Royal) accent and we joked about many tech-terms and "colourful" spelling the Brits used. I recall that Fred joined Itek from Ealing, a very well respected instrumentation company in its day. Like so many others...Taylor-Hobson, Hilger-Watts and GEC-Marconi. American high-tech in those days was the result of many dedicated and diligent individuals like Fred, using their imagination with crude tools like the slide-rule and Peterson's 10-place Log-tables to calculate with (not eat off)...all of which mystify today's scientists from the standpoint of "...how did they do it?" I sometimes wonder myself...but "we" certainly did it! And without PCs or lasers...a-la: Secret satellites, the U-2 and SR-71, Mercury, Gemini and Apollo that bore many optical systems we developed to bring proof back to earth in the images that kept us safe during the cold-war and shared man's space adventures with the world through images we treasure today. Fred will be missed. Regards, Dave Stites St Petersburg FL
