  1. Claude Félix Abel Niépce (1764–1828) was a French inventor and the older brother of the more celebrated Nicéphore Niépce. Claude traveled to England to try to find a sponsor for their internal combustion engine and died there. His brother's later successful development of photography has eclipsed the part played by Claude. [1] Life.

  2. Joseph Nicéphore Niépce (Chalon-sur-Saône, 7 de março de 1765 – Saint-Loup-de-Varennes, 5 de julho de 1833) foi um inventor francês responsável por uma das primeiras fotografias. [1] Dentre outras invenções suas está o Pyréolophore, o primeiro motor de combustão interna, que ele concebeu, criou e desenvolveu com seu irmão Claude ...

    Seeking to obtain positive images, Niépce turned towards compounds that are bleached by light instead of blackened. He then tried with salts and iron oxide, as well as manganese black oxide. Even though he got some results, he stumbled over the fixing problem, which arises when he tried eliminate the initial chemical that had not been transformed b...

    To solve this problem, Niépce tried to find a method that would make him obtain images etched on a base. To do this, he researched the effects of light on acids in the hope to observe their decomposition. Based on these results, he thought he could simply spread acids on calcareous stones, whose strength would vary with light intensity and etch the...

    Niépce stopped his studies on light for almost a year. Following a competion started in France, he tried to find deposits of calcareous stones for lithography (limestone). In September 1816, the two Niépce brothers, communicating by mail, tried out a new fuel for their engine. Using kerosene, they discovered the fuel injection principle, as we know...

    In March 1817, Niépce decidedly took up his research on making images again. While reading chemistry treatises, he focused his attention on the resin of Gaïacum extracted from a coniferous tree. This yellow resin becomes green when exposed to day-light. What made it particularly interesting is that it loses its solubility in alcohol. Niépce underst...

  3. Nicéphore Niépce (born March 7, 1765, Chalon-sur-Saône, France—died July 5, 1833, Chalon-sur-Saône) was a French inventor who was the first to make a permanent photographic image. The son of a wealthy family suspected of royalist sympathies, Niépce fled the French Revolution but returned to serve in the French army under Napoleon Bonaparte .

  4. Joseph Nicéphore Niépce (French: [nisefɔʁ njɛps]; 7 March 1765 – 5 July 1833) was a French inventor and one of the earliest pioneers of photography. Niépce developed heliography, a technique he used to create the world's oldest surviving products of a photographic process.

  5. Claude Félix Abel Niépce, probablement né en 1763 à Chalon-sur-Saône, en France, et mort en 1828 à Kew, en Angleterre, est un inventeur français et le frère aîné de l'inventeur Nicéphore Niépce.

  6. Paris, Novembre 9th, 1806. Presentation, description and plans of the engine invented by Claude and Nicéphore. At first, the Niépce brothers used as an explosive a powder made with the spores of a plant: the Lycopodium (broad moss), then they used coal mixed with resin.
