First wireless communication

In 1894, the first wireless transmission of information using Morse code was demonstrated by Oliver Lodge during a meeting of the British Association at Oxford. A message was transmitted about 150 yards (50-m) from the old Clarendon Laboratory to the University Museum. However, as he later wrote in his Work of Hertz and Some of his Successors, the idea did not occur to Lodge at the time that this might be developed into long-distance telegraphy. “Stupidly enough, no attempt was made to apply any but the feeblest power, so as to test how far the disturbance could really be detected.” Nevertheless this demonstration predated the work of Guglielmo Marconi, who began his experiments in 1896.«
