John Alfred Prestwich
John Alfred Prestwich (* 1874 in Kensington ; † 1952 ) was a British engineer.
He became famous both for film technology equipment and for designing internal combustion engines, which he manufactured in his company JAP .
At the age of 16 he started working for Sebastian Ziani de Ferranti . In 1894 he made his own and built electric apparatus. In 1896 he had contact with the cinema pioneer William Friese-Greene , whom he hired as a “part designer”. Green developed a duplex film projector, but initially it was unsuccessful. From 1897, however, he was able to offer three projectors that had the special transport mechanism for a completely flicker-free motion picture. The film format was 2⅜ inches or 60.325 mm. Prestwich and Green have produced corresponding demonstration positives with a special copying machine.
Prestwich sold film cameras all over the world; the 1898 model 4 already held 500 feet of 1⅜ "raw film (over 150 meters). Prestwich Industries, Ltd also had perforating machines, glueing gauges and accessories in its catalog.
