100 Years Ago: Planetarium Concept Born

100 years ago today, on 1914 February
24, the concept of the projection planetarium was born, at a meeting
of staff scientists of the Carl Zeiss Company in Jena, Germany. Due to
delays caused by the First World War, the first actual planetarium
projector would not be produced until nearly a decade later.
