OTTOMAR ANSCHÜTZ (1846-1907)
Anschütz uses a Geissler vacuum tube to illuminate his #Electrotachyscope {Electrical #Tachyscope}. The instrument was unable because of its construction and design, to be viewed by more than a handful at once.

The Electrotachyscope operated as a large revolving stroboscopic disk. It held around its circumference, the photographs which were illuminated by an initial spark.
