Monkey on Branch

A stereoscopic viewer was invented by David Brewster in 1849, but he could not get British manufacturers interested, so took it to Paris in 1850. There, he showed it to Louis Jules Duboscq-Soleil, who not only manufactured it but also began making his own stereoscopic daguerreotypes including this one. Along with natural history specimens, Duboscq-Soleil also photographed painted portraits and sculptures.
