Langenheim brothers
Also known as: American Stereoscopic Company
Region: United States Period: 1850–1890 Occupation: PublisherFrederick and William Langenheim were brothers of German origin. In 1848 they were registered with a photographic studio in Philadelphia. They produced daguerreotypes and had also acquired a licence to apply the calotype process.
In 1848 they experimented with projecting images on glass. These glass transparencies were called Hyalotypes. The process contributed to increased interest in the magic lantern projector and stimulated its wider use. The Hyalotype also served as an inspiration for Jules Duboscq to begin producing glass stereoviews.
From 1861 onward the Langenheim brothers continued their activities under the name American Stereoscopic Company and focused on the production of glass transparencies for the magic lantern and the stereoscope.
