In February, Saun Farrelly entertained us with the
story of Guglielmo Marconi. He was born in Italy, in
1874, to an Italian father and an Irish mother - his
mother was Annie Jameson whose family owned
the Jameson Whiskey Distillery. He was educated
privately at Bologna, Florence and Leghorn and took
a keen interest in physical and electrical science, and the works of Michael
Faraday
Heinrich Hertz had earlier discovered that electromagnetic waves existed
in the air and that these could be detected over short distances. Marconi
took inspiration from the work of Hertz, and carried out a series of
practical experiments in wireless telegraphy in Italy, sending wireless
signals over a distance of one and a half miles using a coherer.
In 1896 Marconi took his apparatus to England where he was introduced
to William Preece, Engineer-in-Chief of the Post Office, and later that year
was granted the world’s first patent for a system of wireless telegraphy.
He demonstrated his system successfully in London, on Salisbury Plain
and across the Bristol Channel, and in July 1897 formed The Wireless
Telegraph & Signal Company Limited (re-named Marconi’s Wireless
Telegraph Co.).
In 1899 he established wireless communication across the English
Channel. Many scientists were working in the same field but it was
Marconi who realized the potential of the discovery which led him to
take out Patents for
various transmitting
systems, sending the
f
irst wireless signals
across the Atlantic
between Poldhu,
Cornwall, and St.
John’s, Newfoundland,
a distance of 2100
miles.

In 1918, Marconi sent the first signal from England to Australia, which
highlighted the scores of achievements during his lifetime, the greatest
of which was the 'wireless' distress signals which led to the saving of
hundreds of thousands of lives at sea, notably the ‘Titanic Disaster’.
The technology also led to the arrest of Dr Crippin (for the murder of his
wife) on arriving in America.
Marconi received many honours and several honorary degrees and
was awarded the Nobel Prize for Physics (1909) for the development of
wireless telegraphy. He was married twice, having 3 children
and died in 1937.
Next Meetings: On March 4th our topic will be The activities of the Staffordshire Catholics after the Restoration, and on the April 1st the subject of our talk will be The Klondyke Gold Rush.
