Donald's Nephews
Donald's Nephews (1938) is a Donald Duck animated cartoon which features Donald being visited by his three nephews, Huey, Dewey, and Louie. This cartoon is Huey, Dewey, and Louie's very first appearance in animation. The short, and the three nephews, was the idea of Al Taliaferro, the artist for the "Silly Symphonies" comic strip, which featured Donald Duck. The Walt Disney Productions Story Dept. on February 5, 1937, sent Taliaferro a memo recognizing him as the source of the idea for the planned short. Taliaferro subsequently introduced the nephews in his comic strip, which by this time had been renamed "Donald Duck", on Sunday, October 17, 1937, beating the theatrical release of "Donald's Nephews" by almost six months.
Donald Duck universe
Duckburg is home to Yarvard University (a play on the universities of Harvard and Yale), an institution more notable for its athletic teams than for its academic achievements. It also has had international students, like the bey of El Dagga from Egypt, who is mentioned in Yarvard's first appearance; "The Mummy's Ring" by Carl Barks from 1943. One of the things the bey learned at the university was that mummies do not eat. Duckburg is also the home of the Billionaires Club of some of which Scrooge McDuck, John D. Rockerduck and, according to some stories, Flintheart Glomgold are influential members. Duckburg also has a Ritz Hotel, first mentioned in Carl Barks' story "Turkey with All the Schemings" (Walt Disney's Comics and Stories #148, 1953) at which Scrooge McDuck had a business meeting with Donald Duck; who was disguised as the Duke of Baloni, the World's Second-Richest Duck at that time. In the same story Scrooge later buys the Ritz Hotel and he still owns it in Don Rosa's story "Attaaaaaack!" (2000).
