Dr. Suess coined the word “nerd.”
The first documented use of the word Nerd is in the 1950 Dr. Seuss story, If I Ran the Zoo, in which a boy named Gerald McGrew made a large number of delightfully extravagant claims as to what he would do, if he were in charge at the zoo. Among these was that he would bring a creature known as a Nerd from the land of Ka-Troo. The accompanying illustration showed a grumpy humanoid with unruly hair and sideburns, wearing a black T-shirt. A fitting image, these days, for a nerd.
The term originated in the 1950 book “If I Ran the Zoo”. From the book:
"And then, just to show them, 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 American Heritage Dictionary’s word history. Experts ‘maintain that Dr. Seuss is the true originator of nerd and that the word nerd (“comically unpleasant creature”) was picked up by the five- and six-year-olds of 1950 and passed on to their older siblings, who by 1957, as teenagers, had restricted and specified the meaning to the most comically obnoxious creature of their own class, a “square.”’
