Kaiserpanorama
The Kaiserpanorama (or Kaiser-Panorama) is a form of stereoscopic entertainment medium used chiefly in the 19th and early 20th centuries, a precursor to film, invented by August Fuhrmann (1844 – 1925). It was patented by the inventor ca. 1890. There would be a number of viewing stations through which people would peer through a pair of lenses showing a number of rotating stereoscopic glass slides.
