Painter and modeller of miniature period figures, born at Faringdon, Oxfordshire. She studied at the Brussels School of Art, Central School of Arts and Crafts and Slade School of Fine Art. She was married to the art critic and editor of the Burlington Magazine, R R Tatlock. Her friendship with the painter Walter Sickert is well recorded in books on him. He met her at a Roger Fry lecture in 1922 after which he drew and painted her many times in the 1920s, much attracted by her boyish, humorous expression. Hey began to exhibit in group shows about this time. She showed with the LG and Denbighshire Art Society for long periods, as well as with the NS, WIAC and SGA. Her first one-man show was of portrait drawings at Reid and Lefevre in 1933. In 1941 she moved to Wales, after which she concentrated on her period figures, which were shown widely.
