Ludwig Von Drake

Professor Ludwig Von Drake is one of Walt Disney's cartoon characters. He was first introduced as the presenter (and singer of "The Spectrum Song") in the cartoon An Adventure in Color, part of the first episode of Walt Disney's Wonderful World of Color on NBC. Said to be an uncle of Donald Duck, he was supposedly named after either Ludwig von Mises or Ludwig van Beethoven. The character displayed his "expert" knowledge on a variety of subjects in eighteen episodes of the classic anthology series, as well as on a number of Disneyland Records.
