Development and inspirations
After the success of National Comics' new superhero characters Superman and Batman, Fawcett Publications started its own comics division in 1939, recruiting staff writer Bill Parker to create several hero characters for the first title in their line, tentatively titled Flash Comics. Besides penning stories featuring his creations Ibis the Invincible, the Spy Smasher, the Golden Arrow, Lance O'Casey, Scoop Smith, and Dan Dare for the new book, Parker also wrote a story about a team of six superheroes. Each superhero in this team possessed a special power granted to them by a mythological figure.
Fawcett Comics' executive director Ralph Daigh decided it would be best to combine the team of six into one hero who would embody all six powers. Parker responded by creating a character he called "Captain Thunder". Staff artist Charles Clarence "C. C." Beck was recruited to design and illustrate Parker's story, rendering it in a direct, somewhat cartoony style that became his trademark. "When Bill Parker and I went to work on Fawcett's first comic book in late 1939, we both saw how poorly written and illustrated the superhero comic books were," Beck told an interviewer. "We decided to give our reader a real comic book, drawn in comic-strip style and telling an imaginative story, based not on the hackneyed formulas of the pulp magazine, but going back to the old folk-tales and myths of classic times."
The first issue of the comic book, printed as both Flash Comics #1 and Thrill Comics #1, had a low print run in the fall of 1939 as an ashcan copy created for advertising and trademark purposes. Shortly after its printing, however, Fawcett found it could not trademark "Captain Thunder", "Flash Comics", or "Thrill Comics", because all three names were already in use. Consequently, the book was renamed Whiz Comics, and Fawcett artist Pete Costanza suggested changing Captain Thunder's name to "Captain Marvelous", which the editors shortened to "Captain Marvel". The word balloons in the story were re-lettered to label the hero of the main story as "Captain Marvel".
Whiz Comics #2 (cover-dated Feb. 1940) was published in late 1939. Captain Marvel, the comic's lead feature, introduced audiences to Billy Batson, an orphaned 12-year-old boy who, by speaking the name of the ancient wizard Shazam, is struck by a magic lightning bolt and transformed into the adult superhero Captain Marvel. Shazam's name was an acronym derived from the six immortal elders who grant Captain Marvel his superpowers: Solomon, Hercules, Atlas, Zeus, Achilles, and Mercury.
In addition to introducing the main character, his alter ego, and his mentor, Captain Marvel's first adventure in Whiz Comics #2 also introduced his archenemy, the evil Doctor Sivana, and found Billy Batson talking his way into a job as an on-air radio reporter with station WHIZ. Captain Marvel was an instant success, with Whiz Comics #2 selling over 500,000 copies. By 1941, he had his own solo series, Captain Marvel Adventures, the premiere issue of which (cover-dated March 1941) was written and drawn by Joe Simon and Jack Kirby. Captain Marvel continued to appear in Whiz Comics, as well as periodic appearances in other Fawcett books, including Master Comics.
Captain Marvel's first appearance, Whiz Comics #2, did not have any copyright registration or renewal.
Inspiration for Captain Marvel came from a number of sources. His visual appearance was modeled after that of Fred MacMurray, a popular American actor of the period, though comparisons with both Cary Grant and Jack Oakie were made as well. Fawcett Publications' founder, Wilford H. Fawcett, was nicknamed "Captain Billy", which inspired the name "Billy Batson" as well as Marvel's title. Fawcett's earliest magazine was titled Captain Billy's Whiz Bang, which inspired the title Whiz Comics. In addition, Fawcett took several of the elements that had made Superman the first popular comic book superhero (super-strength and speed, science-fiction stories, a mild-mannered reporter alter ego) and incorporated them into Captain Marvel. Fawcett's circulation director Roscoe Kent Fawcett recalled telling the staff, "Give me a Superman, only have his other identity be a 10- or 12-year-old boy rather than a man."
Through much of the Golden Age of Comic Books, Captain Marvel proved to be the most popular superhero character of the medium, and his comics outsold all others. Captain Marvel Adventures sold fourteen million copies in 1944, and was at one point being published bi-weekly with a circulation of 1.3 million copies an issue. Several issues of Captain Marvel Adventures included a blurb on their covers proclaiming the series the "Largest Circulation of Any Comic Magazine".
The franchise was expanded to introduce spin-off characters to Captain Marvel between 1941 and 1942. Whiz Comics #21 (1941) introduced the Lieutenant Marvels: three other boys named "Billy Batson" who could also become adult superheroes. Captain Marvel Jr., the alter-ego of disabled newsboy Freddy Freeman, debuted in Whiz Comics #25 (1941). Mary Marvel, alter-ego of Billy's twin sister Mary Batson, first appeared in Captain Marvel Adventures #18 (1942). In contrast to Captain Marvel and the Lieutenants, both Mary Marvel and Captain Marvel Jr. remained kids in superhero form, and were given their own eponymous books in addition to appearing as the lead features in Master Comics and Wow Comics, respectively. Captain Marvel, Captain Marvel Jr., and Mary Marvel appeared together as a team in another Fawcett publication, The Marvel Family. In addition, there was a talking animal spin-off character, Hoppy the Marvel Bunny, which was created in 1942 for Fawcett's Funny Animals comic book and later given an eponymous series as well.
With Bill Parker having been drafted into World War II, chief writing duties on the Captain Marvel-related comics stories went to Otto Binder by 1942. C.C. Beck remained as lead artist, and he and Binder steered the Captain Marvel stories towards a whimsical tone that emphasized comedy and fantasy elements alongside the superhero action. Other artists associated with the Marvel Family at Fawcett included Pete Costanza, Mac Raboy, Marc Swayze, Kurt Schaffenberger, and Richard Deane Taylor. Otto Binder would write over 900 of the approximately 1,790 Captain Marvel-related stories published by Fawcett. Several of Captain Marvel's enduring supporting characters and enemies—including the non-powered Uncle Marvel, Tawky Tawny the talking tiger, and the villains Mister Mind and Black Adam—were created by Binder during the mid-to-late 1940s.
