Guglielmo Marconi
1874-1939
|
Marconi was born in
Bologna, Italy on April 25th 1874, to an Italian
father and an Irish mother. His mother was Annie Jameson whose
family owned the Jameson Whiskey Distillery in County Wexford. His
work on Rathlin Island and in Ballycastle covered a relatively short
period from June 4 to September 2, 1898,
Marconi himself visited for four days during that time. The
experimental work was carried out by his assistant George
Kemp, who was in turn assisted by Edward Glanville. Also
employed was John Cecil from Rathlin Island. They carried out
experimental transmissions between the east lighthouse on Rathlin
Island and the ‘White Lodge’ house situated at the harbor in
Ballycastle. In doing so they created the historical link
between the town and the pioneering developments that were taking
place in ‘wireless telegraphy’.
Heinrich
Hertz who died in 1894, had discovered that electro-magnetic waves
existed in the air and that
these could be detected over short distances. Sir William
Crookes also predicted that these same electro-magnetic waves could be
used for communication. Marconi had studied physics and took
inspiration from the work of Hertz. He carried out a
series of practical experiments in wireless telegraphy in Italy.
Although Sir Oliver Lodge and Dr Alexander Muirhead claimed to have
sent a ‘wireless’ signal between two Oxford buildings in
1894, it was Marconi who registered the first patent of this
technology. Sir Oliver Lodge had developed a more efficient way
of picking up these electro-magnetic signals than Hertz in the
‘Branley coherer’ and Marconi developed this ability a step
further. In 1885, Captain H. B. Jackson (Royal Navy) had also
succeeded in transmitting a ‘wireless’ signal the length of a ship
which rang a bell, and later in 1886 from ship to ship within the
confines of an harbor. Repeating what Marconi had already done
in 1894, Jackson later met Marconi during experiments on the Salisbury
Plain. At the time many scientist were working in the same field, but
it was Marconi who had realized the potential of the discovery,
which led him to register Patent No. 12039, on June 2, 1896
‘with specification for a ‘wireless’ system using
Hertzian waves’. Some
of his landmarks achievements are as follows: These
are just a few of the scores of events and achievements
during his lifetime.
How or why Marconi came to Ballycastle to undertake the trails for Lloyds is not completely clear. It was certainly related to the fact that ‘wireless telegraphy’ promised to become the most important development in tracking incoming and outgoing vessels. The possibility had come of age when, with Marconi equipped stations all along the coast. All vessels within twenty-five miles of shore could make their presence known and send or receive communications. So apparent were the advantages of such a system that Lloyds in May 1898, entered into negotiations for the setting up of Marconi instruments at various Lloyds stations; and preliminary trial were commissioned between Rathlin Island and Ballycastle.
Marconi went on to develop short wave radio, the basis for most long
distance communications before satellite. He was also awarded a Nobel
Prize for Physics in 1909 and on his death in 1937 was given a state
funeral in his hometown of Bologne. |
