The first surviving daguerreotype by Louis Jacques Daguerre, who gave this founding photographic method his name, from 1837.
In fact, experiments in arresting an image from life, ‘drawing with light’ had been yielding mixed processes and results for years previous to the 1839 announcement of the new medium. Daguerre himself developed the daguerreotype, a unique positive image made on silver-coated copper, using advances made in the field by fellow Frenchmen Nicéphore Niépce and his brother Claude.
