This monographic number offers different perspectives about the educational work of Felipe Segovia Olmo. Formed as mathematician, professor by vocation, but first of all Humanist. Segovia not only founded different educational centers at the forefront of the SEK Educational Institution (Institución Educativa SEK), but is known for implementing pedagogical novelties of great importance, like the Smart Classroom (Aula Inteligente). As a representative figure in the field of educational innovation and teachers' professionalization of the last third of the 20th Century in Spain, this monograph aims to offer other less well-known perspectives, but no less relevant, of his educational lifework.
