John Brian Francis "Jack" Gaughan (September 24, 1930 – July 21, 1985) was an American science fiction artist and illustrator who won the
Hugo Award several times. Working primarily with
Donald A. Wollheim at
Ace Books, and
DAW Books from 1971, his simple linear style brought to life images of such works as
Andre Norton's
Witch World novels and
E. E. Smith's
Lensmen and
Skylark novels (for which he did two related sets of
Pyramid Books covers). His broad visual vocabulary enabled him to render the objects, spaceships and scenes in whatever was presented to him as they were described in the books and stories he illustrated. That was especially an accomplishment as many of these authors drew on their knowledge of esoteric subjects for their imagery. This ability made him very popular among people with an engineering background.
