Over 100 years ago, Guglielmo Marconi demonstrated successfully the sending of signals over a distance without wire, hence the term ‘wireless.’

Before this time, ships had made themselves known to shore stations by a hoist of flags.

A commemorative stone was unveiled in Ballycastle, but it was realised in more recent times that an engineer by the name of Edwin Glanville was the unsung hero of the achievement.

Members of the Glanville family and Marconi enthusiasts met on Rathlin Island to unveil a plaque, giving Glanville and Marconi the recognition they deserved.
