Since its creation, Spéos has shown a great interest in the History of Photography and continues to contribute to its evolution. Spéos has performed and sponsored various activities and publications in this field : • Nicéphore Niépce House (first opened in 2001) Spéos restored the Niépce House, where the world's earliest known photograph was taken. This house, laden with history has been transformed into a museum and a classroom for workshops to pass on to a new generation the knowledge of Niépce and Daguerre’s processes. The publication of the book «Niépce, Correspondances et Papiers» by Manuel Bonnet and Jean-Louis Marignier was edited and published by Niépce’s House in collaboration with Spéos on December 5th 2003. The two-volume work consists of 1600 pages, around 700 authentic documents, half of which were never published before, covering a period from 1761 to 1842. The books cover the life of Nicéphore Niépce and his family. Each document is transcribed in extenso with foot notes added to clarify the texts. >> Visit www.niepce.com In 2007, the Niépce House received sponsorship of the Académie des Sciences. - - - - • A Photo Method : The Stop-System Development of a new method to learn photography : the Stop-System, published in French and English.
