1851 __ Telemetry
Charles Wheatstone (1802-1875)
Comment : Wheatstone had developed several methods of recording distant operations, including the electric thermometer for use in mines and at high altitude, and had had installed experimental magnetic counters at the entrances of the Great Exhibition at the Crystal Palace, Hyde Park, in 1851 so that visitor numbers could be monitored minute by minute. The Universal company introduced for sale Wheatstone’s much improved ‘Recording Instrument for Newspaper Offices and Public Buildings’, an adaptation of the Universal telegraph. This was first used in the London Exhibition of 1862 to count and record electrically on a dial everyone entering through the turnstiles. It was modified to count the copies of ‘The Times’ newspaper as they were printing on its rotary presses, indicating the performance on a dial on the editor’s desk.
