(1944- ) UK illustrator whose work as a commercial designer shows in his sf and fantasy commissions, where he is known for paintings whose meticulous technical proficiency gives substance to images that are often extravagant, sometimes learnedly surreal. In the 1960s and 1970s he specialized in album covers, combining Surrealism with glib competence; in fantasy Illustrations – where some narrative content can be assumed to substantiate the leaps of visual imagination – this smoothness was transformed into dreamlike visions in which deeply strange things seem imminent. Much of RD's early work appears in Views (graph 1975). He won a World Fantasy Award in 1977 as Best Artist.
Later work appears in Magnetic Storm (graph 1984) with his brother, Martyn Dean, The Flights of Icarus (graph 1987) with Donald Lehmkuhl, and in cover illustrations like that for Colin Greenland's Other Voices (1988). [JC]
