York City in early 1898, Porter found work at the Eden Musée, a Manhattan wax museum and amusement hall which had become a center for motion picture exhibition and production and licensee of the Edison Manufacturing Company. While at Eden Musée, Porter worked assembling programs of Edison films, most particularly exhibitions of films of the Spanish–American War, Edison productions which helped stir an outbreak of patriotic fever in New York City. As an exhibitor, Porter had tremendous creative control over these programs, presenting a slate of films accompanied by a selection of music and live narration. Edison Porter joined the Edison Manufacturing Company in November 1900. Soon afterward he took charge of motion picture production at Edison's New York studios, operating the camera, directing the actors, and assembling the final print. He collaborated with several other filmmakers, including George S. Fleming. During the next decade Porter became the most influential filmmaker in the United States. From his experience as a touring projectionist, Porter knew what pleased crowds, and he began by making trick films and comedies for Edison. One of his early films was Terrible Teddy, the Grizzly King, a satire made in February 1901 about the then Vice President-elect, Theodore Roosevelt. Like all early filmmakers, he took ideas from others, but rather than simply copying films he tried to improve on what he borrowed. In his Jack and the Beanstalk (1902) and Life of an American Fireman (1903) he followed earlier films by France's Georges Méliès and members of England's Brighton School, such as James Williamson. Instead of using abrupt splices or cuts between shots, however, Porter created dissolves, gradual transitions from one image to another. In Life of an American Fireman particularly, the technique helped audiences follow complex outdoor movement. Uncle Tom's Cabin, was the first American film to use intertitles which helped the audience follow the story by identifying the scenes and some of the principal characters. The Great Train Robbery and after Porter's next film, The Great Train Robbery (1903) took the archetypal American Western story, already familiar to audiences from dime novels and stage melodrama, and made it an entirely new visual experience. The one-reel film, with a running time of twelve minutes, was assembled in twenty separate shots, along with a startling close-up of a bandit firing at the camera. It used as many as ten different indoor and outdoor locations and was groundbreaking
