On December 19, 1962, Von Drake starred in his only theatrical appearance, a featurette titled A Symposium on Popular Songs, which focused on Von Drake lecturing about music of bygone and contemporary decades, and notably received an Academy Award nomination for Best Animated Short Film.
In the 1970s, Von Drake appeared as the narrator in "Nature's Strangest Oddballs", and starred in a number of commercials promoting Gulf Gasoline, featuring newly recorded voice acting and animation.
Von Drake's raspy, Austrian-accented voice was provided by Paul Frees, who was also well-known as the voice behind the Ghost Host in Disneyland's The Haunted Mansion attraction.
Walt gave Frees a hefty amount of freedom and liberty when it came to shaping Von Drake's personality, as ad-libbing was encouraged, much of which was added to the script.
Ludwig Von Drake was introduced in 1961, with the introduction to Walt Disney's television series Walt Disney's Wonderful World of Color.

A notable recurring goal for the professor has been to discover the source of his nephew Donald's temper tantrums, mostly for the sake of Donald's health.
During many of his classic lectures, Ludwig was known to get sidetracked rather quickly, with the end results being comical shenanigans.
