Directly on the Rennsteig in the Neuhaus district of Igelshieb is the listed Geisslerhaus, the birthplace of Dr. Heinrich Geissler (1814 - 1879). The son of a glass-blower, he is regarded as a pioneer of electrical science and vacuum technology. In about 1857, he developed low-pressure gas discharge tubes (called Geissler tubes after him), with which he laid the foundations for, among other things, fluorescent and X-ray tubes.
Geissler is only one example of the skills of Neuhaus glass blowers, demonstrated in both glass apparatus construction and artistic glass design. So the Geisslerhaus Museum also shows the history of local glass processing up to the present day. The spectrum extends from ampoules through Christmas tree decorations, receiving tubes for radios, flacons, glass springs, hollow and solid glass sculptures from the world of animals and mythology to glass toys and thermometers. What is more, the Museum also presents a selection of the works of two internationally recognised glass designers and honorary citizens of Neuhaus, namely Albin Schädel (1905 - 1999) and Kurt Wallstab (1920 - 2002).
Geissler tubes in action, insights into the restricted living and production conditions in past eras and impressions of the great skills of Neuhaus glass blowers - all this is offered by the Geisslerhaus Museum.
