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.
Duck family (Disney)
Donald's cousin Fethry Duck was created for the Disney Studio Program by Dick Kinney and Al Hubbard and was first used in the story "The Health Nut", published on August 2, 1964. Kinney and Hubbard created Fethry to be a beatnik member of the Duck family; the definition of that term—"a person who rejects or avoids conventional behavior"—is Fethry to a tee. In personality, Fethry is an obsessive New Age thinker, eagerly trying to pursue various new hobbies and lifestyles based on books he has read or TV programs he has seen. Fethry is also quite a blunderer, however, so his new hobbies tend to cause chaos for his friends and family.
