Mary Wollstonecraft was an 18th century British writer and advocate for women's rights. She grew up in poverty but received an education, working as a governess and starting a girls' school. She was the mother of Mary Shelley, author of Frankenstein. As one of the first major feminists, she attacked restrictions on women's freedom and education in her writing. Her most famous work, A Vindication of the Rights of Woman, criticized the poor education available to women, which focused on "ladylike" skills and not intellectual development. It also criticized societal expectations that women should stay at home and argued this limited education made women "silly and vain".
