Voice Figures by Margaret Watts Hughes
Made more than 100 years ago by a Welsh singer named Margaret Watts Hughes — not by her hand but rather using her voice and an Eidophone, a “recording” device of her own invention. She would sing into the Eidophone’s funnel and so make its diaphragm vibrate. She’d then bring this vibrating diaphragm in contact with a glass plate covered in pigment to create these wondrous images, akin to visual sound recordings, or what she called Voice Figures (and the more complex Impression Figures).
