Edward "Ed" Valigursky (1926–2009) was an American illustrator renowned for his depictions of technology and aviation in science fiction, pulp magazines, and fine art. After U.S. Navy service during World War II (1945–1948), Valigursky studied at the Art Institute of Chicago and Art Institute of Pittsburgh on the GI Bill. He began selling illustrations as a student, debuting with the November 1951 Fantastic Adventures cover for Ziff-Davis. By 1952, he relocated to New York as assistant art director under Herb Rogoff, using the pseudonym William Rembach for some works.

Freelancing from 1954, he produced over 100 unsigned Ace Books covers, 49 for Amazing Stories, and 32 for Fantastic, featuring his signature needle-nosed spaceships (e.g., Poul Anderson's We Claim These Stars!, 1959). In 1953, he art-directed Quinn Publications' If magazine. Transitioning to advertising and magazines like Collier's, Popular Mechanics (dozens of 1970s–1980s covers), and NASA illustrations, he retired from commercial art in the 1990s. His aviation fine art—highlighting WWII fighters and carriers—was exhibited at the Smithsonian National Air and Space Museum and RAF Museum.
