Valeriano Orobón Fernández (1901-1936) was a Spanish anarcho-syndicalist theoretician, trade-union activist, translator and poet, who wrote the lyrics of the revolutionary song A Las Barricadas. Born in Cistérniga, Valladolid Province, Orobón was active in labour movement struggles from an early age. An intellectual with a facility for languages, he translated the biography of the well-known German anarchist Max Nettlau written by Rudolf Rocker. He died soon after in Madrid.
