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Invented by Louis-Jacques-Mandé Daguerre and introduced worldwide in 1839, daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images.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.
François Fleischbein
His paintings show a French academic style as well as a sweetness and charm common to 19th-century German painting.
With the invention of the daguerreotype in 1839, Fleischbein also worked as an early photographer, an enterprise in which his wife took part.
