He was born on April 19th, 1914 in Puente de La Reina, Navarra and died in Miami, U.S.A., on October 30th, 2003. In 1927 he emigrated with his family to Cuba, where completed his ecclesiastical career in the San Carlos y San Ambrosio Seminar, where he became a priest in 1938. In 1932 he met José Lezama Lima and in 1933 to Guy Pérez - Cisneros, decissive facts in his literary formation. In 1936 he met the Andalucian poet Juan Ramón Jiménez, who published his poems in his Anthology of Cuban poetry. He sistematically collaborated with the magazines: Verbum, Espuela de Plata, Nadie Parecía (founded by him together with José Lezama Lima), and, finally Orígenes.
In 1940 the Cuban ecclesiastical authorities appointed him to the parish of Nuestra Señora de la Merced (Our Lady of the Mercy), in Bauta. Engaged in succesive and laborious construction works, linked to the most advanced artisitic and literary circles from his times, to a magazine like Orígenes and sent to a church in Havana outskirts, he was unsatisfied with humble construction works, but he invited the most dared visual artist from those year to make the stained-glass church windows and paint the walls of the temple, among them the sculptor Lozano and the painters: Mariano Rodríguez and René Portocarrero. Just finished these reforms and placed such valuable artworks, Carteles magazine, in one of its issues, dedicated its central pages to cover a wide information and description of the afore mentioned labours. Besides, cultural sessions which gathered intellectuals, writers, visual artists were held in his church. Those sessions were one of the most important artistic groups in Cuban culture and in them, as well as in the group publishings Father Gaztelú texts were printed. In 1984, he settled in Miami where he became parish priest of San Juan Bosco Church.
