Philosopher, economist, and social reformer, born in London, UK. He was prominent as a publicist in the reforming age of the 19th century.

He published his major work, A System of Logic , in 1843. In 1851 he married Harriet Taylor, who helped him draft the brilliant essay On Liberty (1859), the most popular of all his works. His other main works include Utilitarianism (1863) and Three Essays on Religion (1874). He was elected to parliament in 1865, campaigning for women's suffrage. He remains of lasting interest as a logician and an ethical theorist.
