Mary Ann Radcliffe wrote her feminist tract The Female Advocate from personal indignation at women's inferior earning opportunities, and her Memoirs from a wish to tell the tale of her woes and struggles. The two are not so distant as at first may seem, since they deal with the same predicament.
Mary Ann Radcliffe also wrote poetry; but the bunch of heterogeneous fictions attributed to her were mostly listed as by 'Mrs Ann Radcliffe' or 'Mrs Radcliffe' before the form 'Mary Anne' was applied to them. It is unlikely, though not impossible, that they were the work of the same person who wrote the feminist tract and the memoir.
Both her date of birth and date of death are not accurately known.
