Mary Wollstonecraft (27 April 1759 – 10 September 1797) was an eighteenth-century English writer, philosopher, and advocate of women's rights. During her brief career, she wrote novels, treatises, a travel narrative, a history of the French Revolution, a conduct book, and a children's book. Wollstonecraft is best known for A Vindication of the Rights of Woman (1792), in which she argues that women are not naturally inferior to men, but appear to be only because they lack education. Wollstonecraft died at the age of thirty-eight, ten days after giving birth to her second daughter, Mary Shelley. After her death, her widower published a Memoir (1798) of her life, revealing her unorthodox lifestyle, which inadvertently destroyed her reputation for almost a century. However, with the emergence of the feminist movement at the turn of the twentieth century, Wollstonecraft's advocacy of women's equality and critiques of conventional femininity became increasingly important. Today Wollstonecraft is regarded as one of the founding feminist philosophers, and feminists often cite both her life and work as important influences.
