Chesley Knight Bonestell, Jr. (January 1, 1888 – June 11, 1986) was an American painter, designer and illustrator. His paintings inspired the American space program, and they have been (and remain) influential in science fiction art and illustration. A pioneering creator of astronomical art, along with the French astronomer-artist Lucien Rudaux, Bonestell has been dubbed the Father of Modern Space art.
