Jaume Miravitlles i Navarra (Figueres, 1906-Barcelona, 1988) was trained as an engineer but he stood out as a politician, journalist, writer, advertiser, great communicator and analizer. His political activity against Primo de Rivera's dictatorship led to his arrest in 1924. In 1925 he participated in the organization of the attack against the king Alfonso XIII. He escaped to France and, established in Paris, he connected with Francesc Macià and Ventura Gassol and took part in the attempted insurrection in Prats de Molló in 1926. In 1930, he came back to Barcelona and was imprisonned since the arrival of the Republic. He worked as a teacher at the Work School of Barcelona. He became affiliated to the Bloc Obrer i Camperol and in 1934 he joined Esquerra Republicana. During the Spanish Civil War he was secretary of the Anti-Fascism militia and the promoter and director of the Propaganda Commissioner since 1939. Persuaded by the advertising value of the image, he created the producer Laya Films in order to give worlwide exposure to the cause of Catalonia and the Republic. In 1939 he exiliated to France, NorthAfrica and Mexico and finally in 1944 he established his residence in New York, where he directed the journal Spanish Information, the Spanish Republican government Newsletter in the exile. He came back to Catalonia in 1962 and continued his intense journalistic production.
