Description
Crova’s Disk, a device for demonstrating wave motion, was designed by Andre Prosper Crova (1833-1907), a professor of physics in France. Rudolph Koenig showed an example at the international exhibition held in Paris in 1867. This example came from the Department of Physics at the University of Alabama. The “Max Kohl” inscription on the frame indicates a date before 1908 when the firm began trading as Max Kohl A.G.
