Wheatstone Electric Motor as a Geissler Tube Rotator Georges Carette, Nuremberg
Antique 19th century victorian wood and brass Wheatstone electric motor used as a rotator for an oxygen Geissler tube. This Early example of this beautiful apparatus are rare. Motor height 8.5\" (=21.5 cm) base diameter 4\" (10 cm) geissler tube holder with holder 26 cm/10.23 inch ( max side Geissler tube 9.84\" (=25 cm)
In 1857, the German glass-blower and physicist Heinrich Geissler developed the first practical high-voltage low-pressure gas discharge tube. Geissler could employ lower air pressures than before, obtained by means of a new mercury vacuum pump of his own design. And he made good use of Ruhmkorff\'s new induction coil, to generate fast sequences of high-voltage pulses to drive the gas discharges.
Apart from its role in physical experimentation, the \"Geissler-tube\" was mostly used for optical art. The artistic Geissler-tubes had a variety of fancy shapes; they employed uranium glass for green fluorescence, and powders and liquids for additional color effects. The Geissler-tube also gave rise to an early form of kinetic art, known as the Geissler-tube rotator: an electric motor which rotates a Geissler-tube at a fairly high speed. Since the Geissler-tube emits a periodic sequence flashes (rather than continuous light), looking at a moving tube does not result in a motion blur, but in a superposition of discrete snapshots.
