José Luis Espejo Pérez
Between 1998 and 2002 he lived in the city of Bath (United Kingdom), a period in which he worked as a screenwriter in several audiovisual companies. Previously (in 1994) he spent eight months in the United States. His knowledge of the cultural reality in these two Anglo-Saxon countries brought him into contact with the two subjects he deals with most in his books: Social Reality and Critical History. He returned to Spain in 2002, to dedicate himself to writing historical essay books, among them, El Conocimiento secreto: Los entresijos de las sociedades secretas  and Los hijos del Edén: toda la verdad sobre la Atlántida.  He made trips to Italy and France (until 2007 and 2008), compiling for 10 years a large amount of documentation on the life and work of Leonardo da Vinci . As a result of this research, he published the book: Leonardo: los años perdidos, and later El viaje secreto de Leonardo da Vinci  and Los mensajes ocultos de Leonardo da Vinci .
