What is kaiserpanorama?

Kaiserpanorama refers to a type of stereoscopic viewer developed by German inventor August Fuhrmann in the late 19th century. It consisted of a circular device with a central axis, which held up to 25 stereographic cards that moved in a continuous loop. The viewer could accommodate up to 25 viewers at once, who would peer into individual viewing holes to see the three-dimensional images. The Kaiserpanorama was first introduced at the Berlin Industrial Exhibition in 1889 and quickly became a popular attraction at fairs, amusement parks, and tourist destinations around the world. The device was named after Kaiser Wilhelm II, in homage to his patronage of the arts and culture in Germany at the time. However, the advent of motion pictures and other forms of entertainment led to the decline of the Kaiserpanorama by the early 20th century. Today, antique Kaiserpanoramas are valued as collectibles and historical artifacts.
