![]() ![]() 1835 Electric telegraph invented by Samuel Morse - Errr, nope. Sam did a simplified code but the telegraph was invented by Sir Charles Wheatstone in 1837, cumbersome and needing 5 wires and keys. 1876 Alexander Graham Bell patents the telephone - Mr Bell being British (Scot actually) then Canadian. 1889 Almon Strowger applies for patent for an automated telephone exchange - but do you know why? He worked as an undertaker! 1907 Lee de Forest patents electrode tube for radio receivers - after Sir John Ambrose Fleming had come up with the thermionic diode in 1905. 1928 Vanivar Bush invents the mechanical computer - some 108 years after Sir Charles Babbage made his difference calculating engine. 1943 Alan Turing, Bletchey Park builds Colossus, an electronic calculator to decipher German communications - the first instruction set driven computer, Turing was a true genius but a pity he was a woofter too and topped himself through shame. You might have mentioned too radio location by Sir Robert Watson-Watt in 1935 and then the cavity magnetron by Randall & Boot in 1940; subsequently free-issued over the pond together with Frank Whittle's jet engine.
