Rimmington was born in Leicester and joined the British Surrealist Group in 1937. She exhibited regularly with the Surrealists and practiced automatic writing and drawing, with some of her poems appearing in Surrealist publications. Rimmington’s paintings are noted for their delicacy and the precise application of paint. Many of her paintings feature images of poetic metamorphosis, with subjects relating to death and the sea, or feature disquieting sexual elements. By 1950, Rimmington had begun to experiment with photography, on which she concentrated in her later years.
