James Henry Schmitz (October 15, 1911–April 18, 1981) was an American writer born in Hamburg, Germany of American parents. Aside from two years at business school in Chicago, Schmitz lived in Germany until 1938, leaving before World War II broke out in Europe in 1939. During World War II, Schmitz served as an aerial photographer in the Pacific for the United States Army Air Corps. After the war, he and his brother-in-law ran a business which manufactured trailers until they broke up the business in 1949. Schmitz is best known as a writer of space opera, and for strong female characters (including Telzey Amberdon and Trigger Argee) that didn't fit into the damsel in distress stereotype typical of science fiction during the time he was writing. His first published story was Greenface, published in August 1943 in Unknown. Most of his works are part of the "Hub" series, though his best known novel is the non-Hub The Witches of Karres, concerning juvenile "witches" with genuine psi-powers and their escape from slavery. Karres was nominated for a Hugo Award. In recent years, his novels and short stories have been republished by Baen Books (which bought the rights to his estate for $6500), edited (sometimes heavily edited) and with notes by Eric Flint. Baen have also published new works based in the Karres universe. Schmitz died of congestive lung failure in 1981 after a five week stay in the hospital in Los Angeles. He was survived by his wife, Betty Mae Chapman Schmitz.

Wallace Allan Wood was an American comic book writer, artist and independent publisher, best known for his work in EC Comics and Mad. Although much of his early professional artwork is signed Wallace Wood, he became known as Wally Wood, a name he claimed to dislike. Within the comics community, he was also known as Woody, a name he sometimes used as a signature. He was the first inductee into the comic book's Jack Kirby Hall of Fame, in 1989, and was inducted into the subequent Will Eisner Award Hall of Fame three years later. In addition to Wood's hundreds of comic book pages, he illustrated for books and magazines while also working in a variety of other areas—advertising; packaging and product illustrations; gag cartoons; record album covers; posters; syndicated comic strips; and trading cards, including work on Topps' landmark Mars Attacks set. For much of his adult life, Wood suffered from chronic, unexplainable headaches. In the 1970s, following bouts with alcoholism, Wood suffered from kidney failure. A stroke in 1978 caused a loss of vision in one eye. Faced with declining health and career prospects, he committed suicide by gunshot three years later. Wood was married three times. His first marriage was to artist Tatjana Wood, who later did extensive work as a comic-book colorist. EC editor Harvey Kurtzman, who had worked closely with Wood during the 1950s, once commented, "Wally had a tension in him, an intensity that he locked away in an internal steam boiler. I think it ate away his insides, and the work really used him up. I think he delivered some of the finest work that was ever drawn, and I think it's to his credit that he put so much intensity into his work at great sacrifice to himself". EC publisher William Gaines once stated, "Wally may have been our most troubled artist... I'm not suggesting any connection, but he may have been our most brilliant".
