 He was a partner in Woodville Latham's Kinetoscope Exhibition Company (later the Lambda Company) during the mid-1890s, working with Latham and his sons Otway and Grey, as well as fellow cinema technicians William Kennedy Laurie Dickson and Eugene Lauste.
William Kennedy-Laurie Dickson (3 August 1860 – 28 September 1935) was a Scottish inventor who devised an early motion picture camera under the employment of Thomas Edison (post-dating the work of Louis Le Prince).

The Kinetoscope is an early motion picture exhibition device.
 The Kinetoscope was designed for films to be viewed by one individual at a time through a peephole viewer window at the top of the device.
 The Kinetoscope was not a movie projector, but introduced the basic approach that would become the standard for all cinematic projection before the advent of video, by creating the illusion of movement by conveying a strip of perforated film bearing sequential images over a light source with a high-speed shutter.
 A process using roll film first described in a patent application submitted in France and the U.S. by French inventor Louis Le Prince, the concept was also used by U.S. inventor Thomas Edison in 1889, and subsequently developed by his employee William Kennedy Laurie Dickson between 1889 and 1892.
 Dickson and his team at the Edison lab also devised the Kinetograph, an innovative motion picture camera with rapid intermittent, or stop-and-go, film movement, to photograph movies for in-house experiments and, eventually, commercial Kinetoscope presentations.
WUMO, formerly Wulffmorgenthaler, is a webcomic and newspaper comic strip created by Danish writer/artist duo Mikael Wulff and Anders Morgenthaler.
