In 1950, Dr. Seuss published a book called “If I Ran the Zoo.” It contained the sentence: “I’ll sail to Ka-Troo, and bring back an IT-KUTCH, a PREEP, and a PROO, a NERKLE, a NERD, and a SEERSUCKER, too!” According to the psychologist David Anderegg, that’s believed to be the first printed use of the word “nerd” in modern English.
The next year, Newsweek noticed that nerd was being used in Detroit as a substitute for “square.” But, as Ander-egg writes in his book, “Nerds,” the term didn’t really blossom onto mass consciousness until The Fonz used it in “Happy Days” in the mid- to late-1970s. And thus began what you might call the ascent of nerdism in modern America.
