First telephone call

The telephone was invented by Alexander Graham Bell (UK), who devised a way of converting human voices into electrical impulses, then back to voices. He filed his patent for the telephone on 14 February 1876 at the New York Patent office, New York, USA. The first intelligible call occurred in March 1876 in Boston, Massachusetts, when Bell phoned his assistant in a nearby room and said 'Come here Watson, I want you'.
