Louis Jacques Mende Daguerre
Daguerre was born on Novemeber 18, 1787. He began his work as an apprentice architect, and at the age of sixteen was an assistant stage designer in a Paris theatre. He knew a lot about handing the light and lighting effects, and supplied the scenic and lighting effects for a number of operas in theatres in Paris. He used a camera obscura as an aid to painting in perspective, which then led him to seek to freeze the image. In 1829he signed up a partnership with Nicephore Niepce. In 1835 he put an exposed plate in his chemical cupboard, and later found out that it had developed. Daguerre concluded that it was due to the presence of mercury vapour from a broken thermometer. This discovery made it possible to reduce the exposure time from eight hours to thirty minutes. In 1837 he found out how to fix the images. This new process was called a Daguerreotype. On January 7, 1839 an announcement was made of the discovery, but the details were not divulged until August 19 when the process was announced to the public. The French government bought the rights to give the information to the world. In 1851 Daguerre died. Death is unknown.
