Michael Buckland's notes on Emanuel Goldberg, with links to other resources.

"Emanuel Goldberg (Portrait) was born in Moscow, Russia, in 1881, a chemist, inventor, and industrialist who contributed to almost all aspects of imaging technology in the first half of the twentieth century: photographic sensitometry, reprographics, standardized film speeds, color printing (moiré effect), aerial photography, extreme microphotography (microdots), optics, camera design (the Contax), the important, early hand-held Kinamo movie camera, and early television technology. He received his doctorate from Wilhelm Ostwald's institute in Leipzig in 1906."
