Richard Leach Maddox

Richard Leach Maddox ( August 4, 1816 *, † May 11, 1902 ) was an English physician and amateur photographer, living in London.

In 1871 Richard Leach Maddox succeeded in the development of the photographic dry plate with a silver -gelatin layer, which corresponded to the sensitivity of the hitherto conventional wet plate. The photographer could from now on any make many dry plates and no longer had to carry his complete darkroom with him. The plates could be industrially prefabricated. This new technology led, among other things, a recovery of travel photography. The made ​​possible by this development separation of recording and development, it is thanks to them that photography was something for everyone. After all, not everyone develops his own films

Charles Bennet found out in 1878 that the sensitivity of silver bromide gelatin dry plate could be increased if the sensitive silver bromide - gelatin layer was heated for some time. Bennett was able to produce panels that allowed for exposure times of a fraction of a second. Thus, the wet plate process was ousted.
