The Independent Moving Pictures Company was founded in 1909 by Carl Laemmle, and was located at 573 11th Ave New York City, and with a studio in Fort Lee, New Jersey. The first movie produced by IMP was Hiawatha starring Gladys Hulette, a one-reel dramashort based on the 1855 poemThe Song of Hiawatha by Henry Wadsworth Longfellow. At a time when leading screen players worked anonymously, IMP performers Florence Lawrence, formerly known as "The Biograph Girl," and King Baggot became the first "movie stars" to be given billing and screen credits, a marquee as well as promotion in advertising, which contributed to the creation of the star system. In the early 20th century, the Motion Picture Patents Company, or the Trust, was fought by the unlicensed independent films, led by Laemmle. Others against the MPPC included Harry E. Aitken, William Fox, and Adolph Zukor. The flexible, stealthy and adventurous independents avoided coercive MPPC restrictions by using unlicensed equipment, obtaining their own film materials, and making movies on the sly. After many of the independents, including IMP, organized their distribution subsidiaries into the Motion Picture Distributing and Sales Company in mid-1910, with Laemmle as their president, the Trust issued an injunction against Laemmle for the camera being used, claiming that it was an infringement on their patents, but eventually lost. Before long, the independents began moving to Southern California, and opened up a West Coast movie-making industry. In 1910, IMP began production in Los Angeles, and had a studio in Hollywood at Sunset Boulevard and Gower Street, which became known as "Gower Gulch" due to the actors dressed as cowboys and Indians waiting on that corner to be cast in Westerns. By May, 1912, the Motion Picture Distributing and Sales Company began to collapse, its supporting production companies removing their distribution needs to other companies or under their own direction. On June 10, 1912, the assets of Independent Moving Pictures were transferred to the newly incorporated Universal Film Manufacturing Company, which undertook to distribute for several of the departing Sales Company producers in continued opposition to the Edison trust. IMP was corporately dissolved but its name continued to be used as a brand name for Laemmle's productions.
