DUBOSCQ, Louis Jules
b. 1817 d.Sept 24, 1886
Duboscq was a French optical manufacturer who was instrumental in a number of innovations. In 1849, together with Foucault, he devised arc lamps for projection. He also manucactured the Brewster stereoscope in 1851.
Duboscq also made an apparatus for enlarging by electric light, and showed it to the Paris Photographic Society in 1861.
In order to make it possible whilst travelling to produce a number of
small pictures on a single plate in a camera, Duboscq built what he called
his Polyconograph camera for travellers. This was an attachment that allowed
for fifteen exposures on each plate.
