William Roger Van Horn (born February 15, 1939) is an American cartoonist. Van Horn debuted professionally in his forties with the black-and-white comic book Nervous Rex (1985-1987). A huge fan of Carl Barks, from 1988 Van Horn became a Disney comics artist and writer, producing for decades Donald Duck and Uncle Scrooge stories (occasionally with scripts by John Lusting), primarily for the northern European market. His son Noel Van Horn has worked extensively as a Disney cartoonist as well.

Keno Don Hugo Rosa, known as Don Rosa, is an American comic book writer and illustrator known for his Disney comics stories about Scrooge McDuck, Donald Duck, and other characters which Carl Barks created for Disney-licensed comic books, first published in America by Dell Comics. Many of his stories are built on characters and locations created by Barks; among these was his first Duck story, "The Son of the Sun" (1987), which was nominated for a Harvey Award in the "Best Story of the Year" category. Rosa created about 90 stories between 1987 and 2006. In 1995, his 12-chapter work The Life and Times of Scrooge McDuck won the Eisner Award for Best Serialized Story.
