For the 1961 Disney movie, see The Absent Minded Professor.

The absent-minded professor is a stock character of popular fiction usually portrayed as an academic with important information, but whose focus on their learning leads them to ignore their surroundings.

An example of an absent-minded professor is Professor Plum from Clue, or Professor Calculus from Tintin. The earliest example of this character type is possibly the story associated with the philosopher Thales, who allegedly walked at night with his eyes focused on the heavens, and as a result, fell down a well.

Another usage of the phrase "absent-minded professor" is common in the English language. Like the phrase itself implies, it is used to describe someone who is so engrossed in their 'own world' that they fail to keep track of their surroundings. It is a common stereotype that professors get so obsessed with their research that they pay little attention to anything else.

The "absent-minded professor" archetype is often mixed with the "mad scientist" one.
