Francesc Ferrer i Guàrdia, Spanish philosopher and academic (born 1849)

Francesc Ferrer i Guàrdia, widely known as Francisco Ferrer, was a Spanish radical freethinker, anarchist, and educationist behind a network of secular, private, libertarian schools in and around Barcelona. His execution, following a revolt in Barcelona, propelled Ferrer into martyrdom and grew an international movement of radicals and libertarians, who established schools in his model and promoted his schooling approach.
