Don Rico was the professional name of Donato Francisco Rico II, an American comic book writer, artist, novelist, and wood engraver whose career in the medium spanned from the Golden Age through the late 1970s. His work as a creator is deeply tied to the foundations of Marvel Comics, where he was a prolific writer and editor during the 1940s and 1950s, contributing to the development of many characters and titles.

Born in Rochester, New York, in 1912, Rico began his artistic training at a young age, studying drawing on scholarship before his family moved to the Bronx. His early career as a fine artist included creating wood engravings for the Works Progress Administration Federal Art Project in the 1930s, works that would later be held in the permanent collections of major institutions like the Metropolitan Museum of Art and the Library of Congress.

Rico entered the comic book industry in 1939, working for various publishers during the Golden Age. He contributed to early iterations of characters such as Daredevil (the Lev Gleason Publications version) and, after joining Timely Comics (the precursor to Marvel), became a regular penciler for Captain America and worked on features including the Human Torch, the Whizzer, and the Sub-Mariner. During this period, he was a significant presence in the Timely bullpen, with contemporaries noting his role in the day-to-day management of the art department.

In the 1950s, as Timely transitioned into Atlas Comics, Rico served as a writer and editor under Stan Lee. He was a primary architect of the company's line of jungle adventure comics, co-creating characters such as Jann of the Jungle with artist Jay Scott Pike, Leopard Girl with Al Hartley, and Lorna the Jungle Queen (later Lorna the Jungle Girl). He wrote extensively for the company's horror, fantasy, and Western titles during this period as well.

Rico’s most lasting contributions to the Marvel Comics universe came in the 1960s Silver Age. Using the pseudonym N. Korok, he scripted stories based on plots by Stan Lee, most notably the Iron Man feature in Tales of Suspense #52 (April 1964), which introduced the character of the Black Widow (Natasha Romanova), a character he is credited with co-creating alongside Lee and artist Don Heck. His other Silver Age work for Marvel included a Doctor Strange story in Strange Tales.

Beyond his work in comics, Rico was a prolific author of paperback novels, penning over sixty books under his own name and various pseudonyms, including Donella St. Michaels and Donna Richards. His later career included screenwriting, teaching college courses on comic book history and technique at UCLA, and co-founding the Comic Art Professional Society (CAPS) in 1977 with Sergio Aragonés and Mark Evanier.

Regarding his association with Japanese anime and manga, the credits for titles such as Marvel Future Avengers and Avengers: Zombies Assemble reference Don Rico as an original creator. This attribution pertains to his foundational work as a co-creator of characters like the Black Widow, whose canonical origins and history he helped establish in the 1960s, rather than indicating direct work as a writer or artist on those specific Japanese productions. His creative legacy is therefore that of a foundational figure in American comics whose character creations and story concepts have been adapted across various global media.
