Carl Robert Fallberg (September 11, 1915 – May 9, 1996) was a Disney Comics artist who wrote and drew many Disney Comics. He was noteworthy for scripting most of the Mickey Mouse serials illustrated by Paul Murry that appeared in Walt Disney's Comics and Stories from the early 1950s to 1973. Many of these reflected his love of railroads. He also specialized in creating colorful characters inhabiting the various exotic locales the serials often were set in. This provided narrative interest that compensated for the generally bland personality Mickey Mouse had in this period. He also created Lil Bad Wolf and wrote some Bucky Bug, Donald Duck and Uncle Scrooge stories. In the 1940s and 1950s, his Fiddletown & Copperopolis comic strip appeared in Railroad Magazine.

Pat McGreal was a prolific writer of Disney Comics for the Egmont Company overseas, much of it later republished in this country. His non-Disney work included three graphic novels for DC/Vertigo: Chiaroscro; The Private Lives of Leonardo DaVinci, Veils and I, Paparazzi. Among the comic books he wrote for were Captain Marvel, Tarzan, The Simpsons, Judge Dredd, The Flash, Justice League, Indiana Jones, Martian Manhunter and Fighting American. He was an Eisner Award nominee and a past president of the Comic Art Professonal Society.
