Claudia was born in Purley, but her family had Welsh roots. She spent much of her life living and working in Wales.
She began her training at the Chelsea School of Art in 1950, and won the Young Person's Prize for art at the National Eisteddfod in Caerffili that year.
In 1953, she married Gwilym Prichard in. She worked for the Workers Educational Association, providing further education to adults in the UK, Australia, New Zealand and Canada.
During the 1980s she travelled extensively in Europe with Gwilym and the children, creating notable works in Skiathos, Provence and in Brittany where they lived for 15 years. She exhibited her work widely in France, including at the Salon de Beaux Arts in Paris and at the Salon de Nantes Biennale. She won first prize in the Salon de Vannes in 1989. She joined the RCA in 1979 and received the silver medal from the Société Académique des Artes-Sciences-Lettres in Paris in 1995.
Her work often focusing on family relationships domestic scenes. The quotidian pleasures and routines of life and its rituals. Cooking and playing music together, holidays on the beach. Ordinary, fleeting moments that become precious memories. Work full of feeling and love.
They returned to Wales in 1999, settling in Tenby. Claudia was made an Honorary Fellow of Bangor University in 2002. Her work is held in many public collections, including the Universities of Bangor and Aberystwyth, and the civic galleries in Southampton and Newport, and the National Museum of Wales.
