1807 – 1858
Harriet Taylor Mill (1807–1858) was a British philosopher, liberal feminist, and intellectual collaborator of John Stuart Mill, whom she married in 1851. She was a forceful advocate for women's rights and individual liberty, whose philosophical contributions shaped the liberal tradition through both her own essays and her influence on Mill's major works. Her essay 'The Enfranchisement of Women' (1851) stands as an early landmark in the philosophical case for women's political equality.
