Joan Peiró i Belis, born on this day in 1887 (also known as Juan Peiró), was an anarchist activist and writer who became Minister of Industry of the Second Spanish Republic during the Spanish Civil War. He was also editor of the anarchist newspaper Solidaridad Obrera and two-time Secretary General of the Confederación Nacional del Trabajo (CNT).

Following the fall of the republic in 1939, Peiró fled to France, where he was turned over to Nazi Germany by the Vichy Regime. Peiró was executed after the Gestapo extradited him to the fascist Franco government in Spain.
