He started his activity at his father’s workshop when he was twelve. There, he made many works that he exhibited in individual and collective exhibitions all over Spain. In 1955, he enjoyed a scholarship of the Ministry of Education and the County Council of A Coruña to study in Paris at the Louvre School, the most important one.
