The first edition of radio was patented in 1896 by Guglielmo Marconi. Marconi was a pioneer of wireless telegraphy. Born in Italy in 1874, he began experimenting with his inventions at the age of 20 after becoming aware of the work of Hertz in electromagnetic waves, also known as radio waves. Marconi identified this area was not popularly pursued by other inventors at the time.
In July 1986 Marconi made the first demonstration of his invention, the radio transmitter and receiver, for the British government. In December 1901, Marconi successfully transmitted the first wireless telegraphy signals across the Atlantic Ocean. He was awarded the Nobel prize in physics in 1909.
The fourth generation of Marconi’s “Type A” microphones were used widely by the BBC from the 1930s onwards. The Type A came to symbolise the BBC.
