The prize was established in 2003 to mark the work of a local artist who has taken up art as a second career later in life.
It honours the work and commitment of Lady Mary Moser who was chair of [email protected], the Oxfordshire Artweeks education charity.
Mrs Chappell’s work will be on display in the Heseltine Gallery at Chenderit School in April, and in her studio, Hamptons in Banbury and Burford Art Gallery during Artweeks, which runs from May 21 to 30.
The prize will be presented on April 14.
She spent many years as principal art teacher at The Warriner School in Bloxham. She said: “I loved working with the young people but teaching and raising a daughter left little time for my own art.
“It wasn’t until I took early retirement that I was able to devote the time to develop my painting and make a profession of it.”
Mrs Chappell, 65, trained as a potter originally and later enrolled on an Oxford University further education course called Walking the Past, an introduction to local landscapes, and Oxfordshire’s hill forts, henges and standing stones.
