Which McDonald’s character was created as a scientist and inventor in McDonaldland?

The Professor was McDonaldland’s scientist and inventor character.

He appeared as an older, intellectual figure among the fictional characters used in McDonald’s advertising. His role was different from characters directly tied to specific foods or restaurant jobs: he represented inventions, experiments, and technical knowledge within the fantasy setting.

The Professor is less widely remembered than Ronald McDonald, the Hamburglar, or Grimace, which can make his identity difficult to recall. He should not be confused with Officer Big Mac, whose character was based on a Big Mac and had a law-enforcement role.

The character illustrates how McDonaldland expanded beyond product mascots into a complete cast with contrasting personalities and occupations.
