On January 7, 1839, members of the French Académie des Sciences were shown products of an invention that would forever change the nature of visual representation: photography. The astonishingly precise pictures they saw were the work of Louis-Jacques-Mandé Daguerre (1787–1851), a Romantic painter and printmaker most famous until then as the proprietor of the Diorama, a popular Parisian spectacle featuring theatrical painting and lighting effects. Each daguerreotype (as Daguerre dubbed his invention) was a one-of-a-kind image on a highly polished, silver-plated sheet of copper.

Daguerre's invention did not spring to life fully grown, although in 1839 it may have seemed that way. In fact, Daguerre had been searching since the mid-1820s for a means to capture the fleeting images he saw in his camera obscura, a draftsman's aid consisting of a wood box with a lens at one end that threw an image onto a frosted sheet of glass at the other. In 1829, he had formed a partnership with Nicéphore Niépce, who had been working on the same problem—how to make a permanent image using light and chemistry—and who had achieved primitive but real results as early as 1826. By the time Niépce died in 1833, the partners had yet to come up with a practical, reliable process.

 

Not until 1838 had Daguerre's continued experiments progressed to the point where he felt comfortable showing examples of the new medium to selected artists and scientists in the hope of lining up investors. François Arago, a noted astronomer and member of the French legislature, was among the new art's most enthusiastic admirers. He became Daguerre's champion in both the Académie des Sciences and the Chambre des Députés, securing the inventor a lifetime pension in exchange for the rights to his process. Only on August 19, 1839, was the revolutionary process explained, step by step, before a joint session of the Académie des Sciences and the Académie des Beaux-Arts, with an eager crowd of spectators spilling over into the courtyard outside.
