Megan Watts Hughes

For the Welsh retired track and road racing cyclist, see Megan Hughes.

Megan [Margaret] Watts Hughes (12 February 1842 – 29 October 1907) was a Welsh singer, songwriter, scientist and philanthropist. Her name appears as Margaret, the equivalent of the Welsh name Megan, in several publications. She was recognised by certain sources as the first to experiment with and observe the phenomenon of visualizing sound, using a device she invented called an "eidophone". The device or instrument produced geometric patterns from the resonance of her voice. As a result, she referred to the images from it as "Voice-Figures." These experiments led to her 1904 book The Eidophone; Voice Figures: Geometrical and Natural Forms Produced by Vibrations of the Human Voice. She demonstrated the instrument for the Royal Society.
