My father (Roy E. Hickey) worked for Graflex for many years as an engineer and designed several of the audio-visual products mentioned in the article. He said the company never made money after it moved to Pittsford (a Rochester suburb). I still have some Graflex prototypes/cameras. The weather wasn't great but the area is beautiful. I rember reading his Fortran manual in 1965 which he was using for designing optics.
