 Additionally, the stories by Al Taliaferro and Ted Osborne are also considered canon by many fans, being that they are the creators of Huey, Dewey and Louie and Grandma Duck, and part of their work precedes Barks' work.The core Duckverse family dates back to the golden age of American animation, generally introduced in Disney shorts, weekly newspaper comics, or comic books of the period as supporting characters for Donald Duck, who premiered in 1934 in "The Wise Little Hen" (but was mentioned as a friend of Mickey's as early as 1931).Donald's nephews, Huey, Dewey, and Louie, first appeared in 1937 in "Silly Symphony".
