She studied art with Philip Conway in Richmond, Alfred Collister at Kingston (she was founder of the New Kingston Group), at Wimbledon and with Patrick Millard at St John’s Wood, also at Central School of Arts and Crafts. Showed at RA, RCamA and elsewhere. She was the main designer of Claverdon Pottery from the mid-1930s. Later work was signed Claverdon or A Bourne Claverdon. Her pottery in Kent was left to the people who had helped her there.
