Flore Célestine Thérèse Henriette Tristán y Moscoso (7 April 1803 – 14 November 1844), better known as Flora Tristan, was a French-Peruvian writer and socialist activist.

[2] Her father, Mariano Eusebio Antonio Tristán y Moscoso, was a colonel of the Spanish Navy, born in Arequipa, a city in Peru.

In 1833 she travelled to Arequipa to claim her paternal inheritance, which was in possession of her uncle, Juan Pío de Tristán y Moscoso.

[3] Around this time, Tristan met and was influenced by the philosophy of the androgynous mystic Simon Ganneau, as well as the occultist writer Éliphas Lévi, her longtime friend.

Tristan would be known as the “mother of feminism and of popular communitarian socialism”,[7] fighting the prejudice and misogyny that powers women's oppression.
