Lab assistant who played a critical role in creating some of the first moving pictures

The lab assistant who played a critical role in creating some of the first moving pictures is W.K.L (William Kennedy Laurie) Dickson. Dickson was a Scottish inventor who assisted Edison. Dickson, at the age of 19, first attempted to work for Edison but he was turned down. It was in 1883 when he finally got to work for Edison in his laboratory in Menlo Park, New Jersey. Thomas Edison, in the year 1888, presented a device that would do “for the Eye what the phonograph does for the Ear". Edison initially filed a preliminary claim on the device called caveat. It was in 1889 that the Kinetoscope, a motion device was also filed for the official claim. It was Dickson who was given the assignment of turning the concept into a reality.
