Charles Nicholas Cuidera, also known as Chuck Cuidera (September 23, 1915 - August 25, 2001), was an American comic book artist best known as the first illustrator of the Quality Comics aviator character Blackhawk, in Military Comics #1-11 (Aug. 1941 - Aug. 1942). Cuidera was also an early artist of the superhero Blue Beetle, yet though he claimed, in his very late years, that he was the Charles Nicholas who created that character, comics historians credit Charles Wojtkowski, who also used the Charles Nicholas pseudonym.

Cuidera grew up in Newark, New Jersey, and after earning art scholarships graduated from Pratt Institute in 1939. Breaking into comic books at Fox Feature Syndicate, where he drew Blue Beetle stories, he shortly afterward migrated to the Eisner & Iger shop.

There he drew the first 11 stories of Blackhawk, the creation of which is also vaguely recorded from the early days of comics, when proper writer-artist credits were not a standard feature. Though reference sources list Eisner as scripter of the first four Blackhawk stories and Dick French beginning with issue #5, Cuidera said he created the character, and that Bob Powell scripted the debut story before turning the feature over to him: "I never drew a script by French. Powell wrote the first one and I wrote the rest until I went into the service". Eisner, who has also said he was involved in Blackhawk's initial writing, hedged the issue, saying, "Whether or not Chuck Cuidera created or thought of Blackhawk to begin with is unimportant [and] the fact that Chuck Cuidera made Blackhawk what it was is the important thing, and therefore, he should get the credit". As the debut artist who designed the characters, Cuidera is confirmably at least the co-creator.

Cuidera served in World War II with the 143rd Regiment of the U.S. Army's 36th Infantry Division. He was awarded the Soldier's Medal for helping rescue 30 soldiers whose boat had capsized off Martha's Vineyard near the geographic designation Paul's Point. He later transferred to the Air Force, and eventually becoming a captain with the 8th Air Division.

During Cuidera's absence, Reed Crandall had become established on "Blackhawk", which would become one of Crandall's signature features. Cuidera segued to work primarily on the Quality character Captain Triumph and later became the company's art director. When Quality sold DC Comics the rights of Blackhawk in 1956, the penciler by then, Dick Dillin, and inker Cuidera continued to work on the character for the new owner. Cuidera became the regular inker on a number of DC features and series, including "Hawkman" and The Brave and the Bold, before leaving comics in 1970.

Cuidera, an avid scuba diver, invented and sold a quick-release diver's weight belt, and also taught scuba in New Jersey YMCAs. He retired with his wife to Ormond Beach, Florida, and was a guest of honor at the 1999 Comic-Con International.

Future industry legend Jack Kirby (1917—1994) used the name Charles Nicholas during his fledgling days, in 1940, adopting that house pseudonym during his three-month run as artist of the Fox Feature Syndicate comic strip version of the Blue Beetle.

Charles Nicholas Wojtkoski (December 6, 1921- June 21, 1985) was an American comic book writer-artist best known as the credited creator of the Fox Comics character Blue Beetle, which in various incarnations has continued through three comics companies and into the 21st century.

The Blue Beetle first appeared in Fox Comics' superhero anthology series Mystery Men Comics #1 (Aug. 1939), with art by Wojtkoski (as Charles Nicholas), though the Grand Comics Database tentatively credits Will Eisner as the scripter. His family has said Wojtkowski "decided in the late 1930s to sell the rights to the character to raise money", but comics creators during that period, with such notable exceptions as Bob Kane (Batman) and Eisner himself (the Spirit), generally did not hold rights to the characters. Charles Nicholas, Wojtkoski variously penciled and inked stories for Timely Comics, the 1940s predecessor of Marvel Comics, where his credits include the character The Defender in USA Comics #1 (Aug. 1941), and stories in Young Allies Comics #1 (Summer 1941), Tough Kid Squad Comics #1 (March 1942), and Comedy Comics (during 1942). Following World War II military service, he returned to Timely, where, beginning with comics cover-dated Spring 1946, he worked on a variety of stories and covers for Captain America Comics, Human Torch Comics, Marvel Mystery Comics, Sub-Mariner Comics (where he drew the backup feature "Blonde Phantom"), and the landmark All Winners Comics #21 (Winter 1946/47), featuring Timely/Marvel's first superhero team, the (hyphenated) All-Winners Squad; Nicholas penciled the cover and the Miss America chapter, and inked penciler Al Avison's lead chapter.

Wojtkoski later worked on the Fawcett Comics jungle character Nyoka, and spent the remainder of his career in-house at Charlton Comics in Derby, Connecticut. There he enjoyed a remarkable 23-year run as penciler on a single creative team, with inker Vince Alascia (another Timely veteran) and writer Joe Gill. The art team would sometimes sign its work Nicholas & Alascia, as in the panel at left.

After Charlton went defunct in the mid-1980s, Wojtkoski drew for the satiric magazine Cracked and for Marvel Comics' The Incredible Hulk comic strip, as well as for the first Transformers hardcover children's books and coloring books.
