an Italian physicist and priest. He is the inventor of the pantelegraph (a.k.a. Universal Telegraph or "all-purpose telegraph"), the predecessor of the modern fax machine. The world's first practical operating facsimile machine ("fax") system put into use was by Caselli. In Florence he studied physics under Leopoldo Nobili. These studies involved electrochemistry, electromagnetism, electricity and magnetism. Caselli started a journal called "The Recreation" in 1851 which was about the science of physics written in laymen's terms.
