In 1915 was a founding partner of V-L-S-E, a film distribution company.
Was one of the first to experiment with 3-D and 70mm films.
Earlier in his career worked for a railroad company. Subsequently employed at an opera house, until he financed an inventor working on motion picture projectors.
George K. Spoor was in the motion picture projection business long before nickelodeons came on the scene. His Kinodrome Company leased short films to vaudeville houses so they could show them as part of their vaudeville shows.
George K. Spoor and inventor Edward Hill Amet built "The Magniscope," a 35mm movie projector said to be the first projector ever designed for use for large audiences.
In 1907, two of Spoor's top technical employees, Donald Bell and Albert Howell, left Essanay Studios and started their own movie-projector company, Bell & Howell.
