went to the United States as an agent for Lincrusta Walton, staying in the country along with his family once his contract had ended. He became the manager for a small group of French artists who produced large panoramas, usually of famous battles, that were exhibited in New York City, Washington, D.C. and Chicago. During this time he began experiments relating to the production of 'moving' photographs, designing a camera that utilised sixteen lenses, which was the first invention he patented. Although the camera was capable of 'capturing' motion, it wasn't a complete success because each lens photographed the subject from a slightly different viewpoint and thus the image would have jumped about, if he had been able to project it (which is unknown). After his return to Leeds in May 1887, Le Prince built a single-lens camera in mid-late 1888. An experimental model was developed in a workshop at 160 Woodhouse Lane, Leeds and used to shoot his motion-picture films. It was first used on 14 October 1888 to shoot what would become known as Roundhay Garden Scene and a sequence of his son Adolphe playing the accordion. Le Prince later used it to film road traffic and pedestrians crossing Leeds Bridge. The film was shot from Hicks the Ironmongers, now the British Waterways building on the south east side of the bridge, now marked with a commemorative Blue plaque. Disappearance In September 1890, Le Prince was preparing for a trip to the United States, supposedly to publicly premiere his work and join his wife and children. Before this journey, he decided to return to France to visit his brother in Dijon. Then, on 16 September, he took a train to Paris but, having taken a later train than planned, his friends missed him in Paris. He was never seen again by his family or friends. The last person to see Le Prince at the Dijon station was his brother. The French police, Scotland Yard and the family undertook exhaustive searches, but never found him. Le Prince was officially declared dead in 1897. A number of wild and mostly unsubstantiated theories were proposed, including: Patent Wars assassination, "Equity 6928"Christopher Rawlence pursues the assassination theory, along with other theories, and discusses the Le Prince family's suspicions of Edison over patents (the Equity 6928) in his 1990 book and documentary The Missing Reel. Rawlence claims that at the time that he
