Author: Jean-Daniel Colladon (1802-1893). Source: This illustration appears in "La Nature" magazine in 1884 and it is reproduced in modern-day accounts of the history of fiber optics including and at the Wayback Machine. Collodon first described the system in an article in "Comptes Rendus" 1842, and described it again in 1884 in "La Nature". In the above illustration, water comes out of a short spout on the watertank and then falls through open air, as in a fountain. The device on the illustration's lefthand side produces light and directs a beam of light into the watertank. The demonstration of this "light fountain" needs to be done in a darkened room to see the effect.
