==Inventor and film innovator==
At age 19 in 1879, William Dickson wrote a letter to American inventor and entrepreneur [[Thomas Edison]] seeking employment. He was turned down. That same year Dickson, his mother, and two sisters moved from Britain to Virginia.<ref name="ReferenceA">{{cite book |last1=Spehr |first1=Paul C. |title=Dickson, William Kennedy Laurie |date=2011 |publisher=Oxford Dictionary of National Biography |url=https://doi
Initial attempts were focussed on recording micro-photographs on a cylinder. In late 1889, inspired by a recent encounter with [[Étienne-Jules Marey]], Edison came up with a fourth caveat and ordered the team to change direction to work with rolls of film. William Dickson collaborated with the Eastman company to develop a practical [[celluloid|celluloid film]] for this application. Initially using 19mm film, fed horizontally, shooting circular images, Dickson eventually settled on [[35mm movie film|35 mm]] film with a 1.33:1 picture ratio, a standard format which is still in use to this day in cinema.<ref>{{Cite book|last=Spehr|first=Paul C.|url=https://www.worldcat.org/oclc/946887787|title=Moving images : from Edison to the webcam|others=Fullerton, John, 1949-, Söderbergh-Widding, Astrid., Stockholms universitet.
