Flora Tristan, French author and activist (d. 1844)

Flore Celestine Thérèse Henriette Tristán y Moscoso better known as Flora Tristan (7 April 1803 – 14 November 1844) was a French-Peruvian socialist writer and activist. She made important contributions to early feminist theory, and argued that the progress of women's rights was directly related with the progress of the working class. She wrote several works, the best known of which are Peregrinations of a Pariah (1838), Promenades in London (1840), and The Workers' Union (1843).

Tristan was the grandmother of the painter Paul Gauguin.
