…In the past, many mechanical solar orbs were made, but today, a planetarium is a device that projects celestial bodies inside a round ceiling in the same way as the actual starry sky. The first planetariums were made in the early 1910s, when O. von Miller, director of the Deutsches Museum in Munich, Germany, wanted to make a device that would show the principles of celestial motion, and after consulting with M. Wolf, then director of the Heidelberg Observatory, commissioned Carl Zeiss Optical Company to make it. W. Bauersfeld and others at the company completed the development, and in the summer of 1923, it was temporarily unveiled in a 16m diameter dome on the roof of the Zeiss building, where it was met with great acclaim. At the time, the machine could only display the starry sky as seen in Jena or Munich, but it was soon improved to display the starry sky at any latitude around the world, and various other improvements were made. … *Some of the terminology that mentions "Bauersfeld, W." is listed below.
