This is a malicious definition used to identify intellectual persons, particularly referring to those, who are too absorbed by their thoughts and get distracted. The definition was minted by Richard Nixon in 1952, the Republican candidate at Presidency. He used this expression to contemptuously refer to Adlai Ewina Stevenson II (1900-1965), the US Democratic politician of high influence and remarkable cultural background. His had was almost completely bald (indeed, it is used to describe a large forehead), which is considered to be the sign of a person with particular intelligence. Stevenson was undoubtedly an enlightened Governor of Illinois. He reformed the State Police and fought to gamble. He also declared himself against nuclear experiments during the Cold War, which cost him one of the two defeats against Eisenhower in the race to the White House.
