Santiago de Cuba teacher Juan Bautista Sagarra Blez developed an outstanding work for the education of Santiago de Cuba and Cuba between 1830 and 1870. His work as a writer of school texts (especially his text collection Librería de los Niños Cubanos), director of schools (technical, preparatory and private) and his contribution to the economic and social development of the locality stand out. The Cuban Children's Bookstore (18 titles)-the first collection of school texts written by a Creole educator, represents a solid link in the general, renovating, scholastic-pedagogical, didactic-methodological work, and in particular in the production of school texts for Cuban children and youth. In the second half of the 19th century, he founded two of the most important technical centers of his time: the General Preparatory School and the School of Surveyors, Quantity Surveyors and Master Builders, schools that were characterized by the use of innovative teaching methods and the experimental-practical nature of their classes.
