Quoc: The first documented appearance of the word nerd is as the name of a creature in Dr. Seuss's book If I Ran the Zoo (1950), in which the narrator Gerald McGrew claims that he would collect "a Nerkle, a Nerd, and a Seersucker too" for his imaginary zoo. The slang meaning of the term dates to the next year, 1951, when Newsweek magazine reported on its popular use as a synonym for drip or square in Detroit, Michigan.
