Born in Oldham, Lancashire, Muriel trained at Manchester Regional College of Art before moving to the Channel Isles where she lived for 10 years and worked at the Jersey Potteries. Moving to Borth in mid-Wales, where she lived for more than 30 years, her house was only a few steps from the beach and provided Muriel with the setting for her paintings. Expressionist in style, her grey, green palette reflected the often wet shores of Cardigan Bay and the village of Borth. She was a figurative painter, working in oils on canvas or board.
Muriel passed away in December 2020, at the age of 89.
