GENERAL KNOWLEDGE

Detailed explanation-1: -Edison’s laboratory was responsible for the invention of the Kinetograph (a motion picture camera) and the Kinetoscope (a peep-hole motion picture viewer). Most of this work was performed by Edison’s assistant, William Kennedy Laurie Dickson, beginning in 1888.

Detailed explanation-2: -Seeking to provide a visual accompaniment to the phonograph, Edison commissioned Dickson, a young laboratory assistant, to invent a motion-picture camera in 1888. Building upon the work of Muybridge and Marey, Dickson combined the two final essentials of motion-picture recording and viewing technology.
