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 laboratory 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.

||2010: Richard Darwin Keynes dies ... physiologist who did pioneering work on the mechanisms underlying the conduction of the action potential along nerve fibres. Early in his career, he worked with the giant nerve fibers of squid, which would help discover how nerve impulses are transmitted in all animals. In later resarch, he determined how electric eels project electric fields outside their bodies. Keynes was the first to use radioactive sodium and potassium tracer atoms to follow the movements of these atoms when an impulse is transmitted along a nerve fibre. He has written extensively about the life and work of his great-grandfather, Charles Darwin, beginning with The Beagle Record (1979).
