Hannes Bok, pseudonym for Wayne Francis Woodard , was an American artist and illustrator, as well as an amateur astrologer and writer of fantasy fiction and poetry. He painted nearly 150 covers for various science fiction, fantasy, and detective fiction magazines, as well as contributing hundreds of black and white interior illustrations. Boks work graced the pages of calendars and early fanzines, as well as dust jackets from specialty book publishers like Arkham House, Llewellyn, Shasta Publishers, and Fantasy Press. His paintings achieved a luminous quality through the use of an arduous glazing process, which was learned from his mentor, Maxfield Parrish. Bok shared one of the inaugural 1953 Hugo Awards for science fiction achievement .
Wayne Woodard was born in Kansas City, Missouri. His parents divorced when he was five and his father and stepmother, strict disciplinarians, discouraged his artistic efforts. Once he graduated high school, in Duluth, Minnesota, Bok cut off contact with his father and moved to Seattle to live with his mother. There he became active in SF fandom, including the publication and illustration of fanzines. It was in connection with these activities that he originated his pseudonym, first Hans, then Hannes, Bok. The pseudonym derives from Johann Sebastian Bach .
