Der Triumph der Relativitaetstheorie: Bestaetigung der ART

Stereo Comparator from Carl Pulfrich
Prototype, Zeiss Company, 1899

The stereo comparator allows for the comparison of two photographic plates. By looking at two photos taken at different times, the actual or apparent movement of astronomical objects can be ascertained. According to Einstein, the positions of stars during an eclipse of the Sun should appear to shift since the light rays are bent by their proximity to the Sun.
