Guglielmo Marconi is widely considered to be the “father of radio”. The Italian inventor shared the Nobel Prize in Physics in 1909 and built a large multinational company to develop and exploit his inventions. He even helped set up Vatican Radio for the Pope.
As my wife and I started to clear out some things from home I came across this item from my currency collection. It’s a 2,000 Lire (pre Euro) note from Italy featuring a large portrait of Marconi on the front.
Don’t get too excited all of the digits on the note. In 1990, 2,000 Lire was worth about $1.77!
On the back there are several images, all of which illustrate some aspects of his radio inventions and adventures.
On the lower right there appears to be a spark gap transmitter, typical technology in the earliest days of radio. On the lower left stand four enormous towers, undoubtedly holding up the large amount of wires making up the antenna being used. Early Marconi wireless stations sported numerous wooden towers up to 200 feet tall. The concentric squares in the middle likely represents a loop antenna.
At the top sits the Elettra, Marconi’s personal yacht. The vessel served as a seaborne laboratory for Marconi after World War I. How important was Elettra to Marconi and his efforts? According to the man himself, very important.
Without Elettra it would have been impossible to carry out my experiments in the Mediterranean and in the Atlantic; I would not have been able to continue and develop my research into short wave transmissions. With my seaborne laboratory – unique in the world – I have been able to realise my dreams. For example, how to beam (direct) a radio signal and to use radio for navigational purposes. This yacht has not only made me independent, but also freed me from distractions and the curiosity of others. I have been able to work at any time of the night and day and move around in a way that would have been quite impossible on dry land.
