Who of the following invented movie projector ?

Result
Your answer: —  Â·  Correct: D
Explanation

Thomas Edison is credited with the invention of the movie projector through his laboratory's development of early motion picture technology. While his initial invention, the Kinetoscope (1894), was a peep-hole viewer for single individuals [t2][t3], his laboratory also developed the Kinetograph camera [t2][t9]. To compete with the Lumière brothers' Cinématographe, which could project films for an audience, Edison eventually marketed the Vitascope, a successful early movie projector [t3]. Other options are incorrect: Alexander Graham Bell is famous for the telephone [c3], Benjamin Franklin for electricity and the lightning rod, and J. L. Baird (John Logie Baird) for the invention of the mechanical television in the 1920s [t6][t8]. Although the Lumière brothers and Woodville Latham also made significant contributions to projection, Edison remains the primary inventor associated with the commercialization of the movie projector in this context [t1][t3].
