Daguerre was born in Cormeilles-en-Parisis, France. He was an artist and a chemist, recognized for his invention of the daguerreotype process of photography. After years of experimentation Daguerre announced the last perfection of the Daguerreotype, in 1839, together with the French Academy of Sciences. Daguerre's patent was acquired by the French Government and in August the invention was a called a Free Gift to the World.
Daguerre first exposed silver-coated copper plates to iodine, obtaining silver iodide. Then he exposed them to light for several minutes, coated the plate with mercury vapor heated to 75° Celsius and finally fixing the image in salt water. These ideas led to the famous Daguerreotype and the development of the first permanent photograph that was made in 1826 by Joseph Nicéphore Niépce.
The resultant plate produced an exact reproduction of the scene. The image was laterally reversed the way images in mirrors are, unless a second mirror was used during exposure to flip it. The image could only be viewed at an angle and needed protection from air and fingerprints. Since then picture development has changed, but the main principles stayed the same.
Daguerre's name is one of the 72 names inscribed on the Eiffel tower.
