On a summer day in 1827, Joseph Nicephore Niepce made the first photographic image with a camera obscura. Louis Daguerre was the inventor of the first practical process of photography. In 1829, he formed a partnership with Joseph Nicephore Niepce to improve the process Niepce had developed. In 1839 after several years of experimentation and Niepce's death, Daguerre developed a more convenient and effective method of photography, naming it after himself - the daguerreotype.
Joseph N. Niepce's world famous partner and colleague was Louis-Jacques-Mande Daguerre. Joseph and Louis created a process to make heliography faster.
The father of Joseph Nicephore Niepce was Claude Niepce, and his mother was Claudine Josephe Barault. He also had a brother named Claude-Felix-Abel Niepce, who was an author and an inventor.
