Daguerreotype
Invented by Louis-Jacques-Mandé Daguerre and introduced worldwide in 1839, daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images. In the late 20th century, there was a revival of daguerreotypy by a small number of photographers interested in making artistic use of early photographic processes.
Filippos Margaritis
Filippos Margaritis (1810–1892) is generally acknowledged to have been the first Greek photographer, whose earliest daguerreotypes, of the Acropolis of Athens, date from 1847. Having studied painting in lithography in Paris, he opened a studio in [Athens] in 1837 and began teaching at the School of Fine Arts in 1842. He learned the techniques of the daguerreotypes from the French photographer Philibert Perraud who arrived in Greece in 1847, and in turn passed on his knowledge to the students of Athens Polytechnic around 1850.
