Mary Hays (1759–1843) was an autodidact intellectual who published essays, poetry, novels and several works on famous (and infamous) women. She is remembered for her early feminism, and her close relations to dissenting and radical thinkers of her time including Robert Robinson, Mary Wollstonecraft, William Godwin and William Frend. She was born in 1759, into a family of Protestant dissenters who rejected the practices of the Church of England (the established church). Hays was described by those who disliked her as 'the baldest disciple of Wollstonecraft' by "The Anti Jacobin Magazine", attacked as an 'unsex'd female' by clergyman Robert Polwhele, and provoked controversy through her long life with her rebellious writings. When Hays's fiancé John Eccles died on the eve of their marriage, Hays expected to die of grief herself. But this apparent tragedy meant that she escaped an ordinary future as wife and mother, remaining unmarried. She seized the chance to make a career for herself in the larger world as a writer.
