The daughter of Barbara Hepworth and Ben Nicholson, Rachel typically paints landscapes and still lifes that are clearly influenced by them. However, she has developed her own unique style, which is much sought after. There are obvious echoes from the St Ives School in general but more important is the place itself; she is influenced by the inside and outside of the space she lives and paints, which is her flat in St Ives.
It was not until her mother died in 1975 that Rachel began to paint. At her first London exhibition in June 1980, her father commented on Still Life on Navy Blue 1979: 'I had never realised she could paint so well.' Her work has been shown in mixed exhibitions at Milton Keynes Exhibition Gallery and Beaux Arts Gallery, Bath, both 1981 and Crane Kalman Gallery 1983. She has had a series of solo shows at Montpelier Studio. Sansom & Co published a monograph of her work in 2010.
