The son of a fashion designer mother and a British Army engineer father, Dean spent most of his childhood in Greece, Cyprus, and Hong Kong. Returning to England in 1959, he earned a national diploma of design from the Canterbury School of Art. Continuing his training at the Royal College of Art Furniture School in 1965, he graduated three years later. Dean's earliest experience with music came when he designed furniture for Ronnie Scott's Jazz Club in London. Although he began designing album covers in 1971, he has remained active in furniture design. In 1975, he and his brother collaborated on an elaborate stage set for Yes. Dean reached his apex with his cover for Asia's self-titled debut album in 1982. The album was later voted Second Most Successful Album Cover by readers of Rolling Stone.
While painting and furniture design continue to require most of his attention, Dean has increasingly veered toward other artistic outlets. His full-size prototype of curvilinear house design was exhibited at the International Ideal Home Exhibition in Birmingham, England. He has designed virtual-reality simulators for software company Imagine. ~ Craig Harris, Rovi
