||1851: Oliver Joseph Lodge born ... physicist who perfected his “coherer” to act as a radio-wave detector, the essential part of an early radiotelegraph receiver. On 14 Aug 1894, he made the first demonstration of wireless transmission of information using Morse code at a meeting of the British Association at Oxford. He transmitted a message about 150 yards from the old Clarendon Laboratory to the University Museum. He provided his laborary facilities to conduct the first clinical use of X-rays in England (7 Feb 1896), at the request of surgeon Sir Robert Jones (1855-1933), to examine the wrist of boy who had accidentally shot himself. Lodge invented electric spark ignition, and investigated psychic phenomena with his friend Sir Arthur Conan Doyle. Pic.
