The Thanhouser Company (formerly the Thanhouser Film Corporation) was one of the first motion picture studios, founded in 1909 by Edwin Thanhouser. It operated until 1920. It produced over 1,000 films, but several dozen of the films were of small filler subjects, educational or documentaries. Many of these smaller subjects were listed as a quarter or half a reel in length and received very little critical review or analysis by film critics and the media.
