Immediately following his high school studies in 1956, Fernando Fernández started drawing for French and British publishers through the Selecciones Ilustradas agency. In 1958, he followed his parents to Argentina, where he cooperated on magazines like El Gorrión, Tótem and Puño Fuerte. Meanwhile, he drew romance stories for the British magazines Valentina, Roxy and Marilyn through Toutain's agency. He returned to Spain in 1959, and produced a large amount of war stories for Fleetway in London.
By the mid-1960s, Fernández focused on his illustration jobs and painting, but returned to the comics scene in 1970. Between 1970 and 1973 he drew the humorous strip 'Mosca' for Diario de Barcelona, and, between 1973 and 1975, his black-and-white comics were published in US magazine Vampirella. He also produced educational comics for the publishing house Afha. In 1979 Cepim published his 'L'uomo di Cuba' in Italy. This was called 'Cuba, 1898' in its 1980 Spanish version. He started the experimental series 'Círculos' in 1979. In 1980, Fernández produced 'Zora y los Hibernautas', a story first serialized in the Spanish magazine 1984, and later translated for Heavy Metal in the USA.
In 1982, Fernández created a pictorial version of Bram Stoker's 'Dracula' for the Spanish version of Creepy. In 1983 he adapted some SF tales for the Bruguera's book 'Firmado por: Isaac Asimov'. For Zona 84, he produced 'La Leyenda de las Cuatro Sombras' with Carlos Trillo. This medieval fantasy was followed by a number of reprinted and new short stories, the series of illustrations 'Galería de Personajes Fantásticos' and two serials of 'Argón, el Salvaje'.
Fernández was also present in Comix Internacional and Rambla. Another adaptation of an Asimov's work, 'Lucky Starr- Los Océanos de Venus', appeared in the fifth issue of Gran Aventurero in 1989. Between 1989 and 1990, he published part of the series 'Zodíaco' in Tótem (second run) in Spain. The series also made its way to European publishers Eura (Italy) and Semic Press (Scandinavia). A serious heart disease made it necessary for him to count on some help to complete his late works. This last stage finished in the early 1990s, after which Fernández returned to his painting and illustration work. He passed away in Barcelona in August 2010, at the age of 70.
