Cook and Wheatstone's 5-needle telegraph, 1837 (1915). The 5-needle telegraph was the first successful electric telecommunication device and was patented by Charles Wheatstone and William Cooke. It first saw service on the newly-developing railways, and by 1838 the telegraph was sending public telegrams as well as Great Western Railway messages between London and West Drayton, a village 21km (13 miles) to the west.
