Abbe Giovanni Caselli (1815 – 1891),Italian priest and professor of physics,invented the first practicable telefax machine,the pantelegraph. Its use of a large pendulum overcame the synchronisation problems between the transmitter and receiver found on the existing telefax devices of Bain and Bakewell. It was capable of sending and receiving both written script and drawings. Following a successful demonstration in 1861 Napoleon III ordered the pantelegraph to be used on the French national telegraph service. It ws also used in Great Britain from 1863 and in Russia from 1864 | |
