The history of the name Baader in Astronomy dates back to the year 1852, when Michael Baader opened an Optical Manufacturing Company in the middle of Munich, after having worked since 1838 in the optical glass works company of "Martin Woerle" and being married with Woerle's daughter. Woerle had gained deep knowledge in the production of optical glass and the secrets of production and testing of achromatic lenses under direct supervision of Josef von Fraunhofer, one of the founders of modern optics and inventor of the "German Mount". Baader Telescopes won prizes for excellent optics and mechanical workmanship at a number of International Industrial Fairs of that time from Berlin to Paris. Seven telescopes of Michael Baader are still to be seen at the present company as well as the prize awarding documents. Claus Baader, the founder of the modern company Baader Planetarium, had designed a sophisticated orrery in the early sixties, which was patented in 1966. It was one of the first astronomical instruments of German origin to be tested in the magazine "Sky and Telescope".
