Every year, the world pays tribute to Guglielmo Marconi, the inventor and businessman who brought about something that is fundamental to the modern way of life – wireless communication.

Our wi-fi, smartphones, TV, microwaves, radar and many more inventions owe a massive debt to the man who started it all, in his first two factories in Chelmsford.

This year, Marconi Day is celebrated on Saturday 23 April at Sandford Mill, near Chelmer Village.

The Mill is the home of Chelmsford Museum’s industrial collections.

Admission for adults is just £2, and it is free for children to come and learn about their city’s Marconi heritage.

Light refreshments will be provided by the Friends of Chelmsford Museums.

Nick Wickenden, Museums Manager at Chelmsford City Council, said: “We tell the main story of Chelmsford’s debt to Marconi at Chelmsford Museum, but our reserve collections are based at Sandford Mill.

"This is one of the few opportunities for the public to come and explore treasures such as the Marconi Hut – the first broadcasting station in the world – or equipment made in Chelmsford which is identical to that used on the Titanic and later ships.”

Councillor Julia Jeapes, Cabinet Member for Museums, said: “Sandford Mill is a real gem.

"It’s quite spine-tingling hearing the Chelmsford Amateur Radio Society contacting other radio enthusiasts all over the world from the very broadcasting hut where it all started, back in 1922.

"I look forward to meeting the Marconi veterans who will be on hand to demonstrate morse code, and seeing the working original TV cameras.”
