Wearing a sailor shirt, cap, and a red or black bow tie, but no trousers (except when he goes swimming), Donald Fauntleroy Duck was "born" June 9, 1934--75 years ago--when he debuted in "The Wise Little Hen", a Silly Symphony cartoon.
Donald's most famous trait is his easily provoked and occasionally explosive temper. He is easily calmed down by his beloved Daisy who can simply soothe his brow to make him happy. Yet, Donald is a lovable character with a good heart who usually tries to do the right thing. He takes humiliation and keeps on going. He never backs down from a fight. Donald may be hard to understand most of the time, but he always has a lot to say.
Donald's voice was performed by voice actor Clarence "Ducky" Nash up to 1985. It was largely this semi-intelligible speech that would cement Donald's image into audiences' minds and help fuel both Donald's and Nash's rise to stardom.
He was featured in over 128 cartoons in the 1940's (more than Mickey Mouse) and was the lesser-known member of the Three Caballeros from 1944. He is also very well known from Duck Tales which was on television from 1987-1990. And for those who are not sure where Donald lives, well of course, it is in Duckburg, Calisota USA.
Many happy returns, Donald F Duck!
