In 1857, the Geissler tube (low-pressure gas discharge tube) was invented by Heinrich Geißler, who was born in Neuhaus am Rennweg. Since its development, the tube has been used in a wide variety of technical fields. Without it, today we would not have fluorescent lights, cathode ray tubes or x-ray tubes, to name just a few of its uses.
In 1876, Robert Götze, who was born and raised in Cursdorf and a student of Heinrich Geißler, opened a business in the university city of Leipzig. He brought his nephews, the brothers Preßler, into the family business and educated them. At the turn of the century, Otto and Rudolf Preßler also opened companies, in Leipzig and Cursdorf respectively. These three firms, through their developments in thermometry, x-ray technology, gas discharge plasma physics and photo electronics, won fame and renown on a global stage.
Exceptionally handcrafted manufactured Geissler tubes are on display in the newly refurbished Historic Glass Apparatus Museum Cursdorf, located in the village community centre. Unique in Germany, the tubes are not only exhibited, but are also presented as working models. Marvel at the fascinating effects of the different apparatuses!
