Sweetheart Viewer

Home » Stereoscopes » Chain-based stereoscopes » Sweetheart Viewer

This chain-based stereoscope has holders with lenses on both sides, allowing two people to view stereoviews simultaneously. This type of stereoscope was therefore called “Sweetheart Viewer”, as someone could enjoy stereoviews together with his or her sweetheart. Sweetheart Viewers were mainly manufactured in the 19th century.

The bottom of the stereoscope contains a paper label of Adolphe Lesage (1843–1881). French-born Lesage was a print seller, frame maker, publisher and photographer in Dublin. He was the seller of the stereoscope, but the stereoscope was manufactured by Patrick Meagher (1829–1897)1 in London. Meagher was known as a manufacturer of high-quality cameras, including stereo cameras2.
