Guglielmo Marconi (1874 - 1937)
In 1895, Marconi built a transmitter and
receiver in his house, sending signals from one end of the house to the other.
Later that year, he reportedly transmitted to his garden, then to a listening post 1.5
When the Italian government refused to
finance his work, Marconi moved to England. His goal was to transmit across the
Atlantic Ocean. Marconi set up operations in several places. Among them,
Lavernock, near Porthcawl, Wales; Poldhu, Cornwall, England; Holy
Head, Wales; and St. John's, Newfoundland, Canada.
On May 13, 1897, Marconi
transmitted wireless signals from Flatholm Island, just off the coast of Wales
to Lavernock. In conjunction with W.H. Preece, this led to the development of
the first practical wireless transmission system to be used for commercial
On April 26, 1900, Marconi
received a patent (Number 7777) from the British Government.
On May 21, 1901 the listening post set up Marconi at
Queens Park, Holyhead picked up what may be the first ever ship-to-shore radio message from
the middle of the Atlantic.

A ship called SS Lake Champlain was going from Liverpool to Halifax, Nova
Scotia. The attempt was made to make a test radio transmission from the ship to
Crookhaven in Southern Ireland, but instead contact was made with the Marconi
post at Holyhead. An account of this reception and history can be found here.
The station was thought to have been demolished after the second world war
but was found to be still in existence and apart from the mast (ariel) the house
looks the same as it did in 1901.
In November 1901, Marconi installed a new
transmitter at Poldhu,
said to be 100 times
more powerful than any other transmitter then in existence.
Then, on December
12, 1901, he
received signals from across the ocean, ushering in a new age of
communication over long distances. This truly can be said to be the invention
that "shrunk the world."
Over the coming years, Marconi built a
major corporation that dominated wireless telegraphy for some years. The Marconi
company today is still a force in the electronics industry.
Among his other achievements was the 1909
Nobel Prize for Physics.
Guglielmo Marconi died on July
