nerd: [20] It seems likely that nerd, a term for a dull, socially inept or otherwise obnoxious person that appeared in US slang in the early 1950s, was inspired by a whimsical creature called a ‘nerd’ that was invented by the American children’s author ‘Dr Seuss’ (Theodore Seuss Geisel (1904–91)) and introduced by him in his book If I Ran the Zoo (1950): ‘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!’ In thinking up the word he may have been influenced by Mortimer Snerd, the name of a dummy used by the American ventriloquist Edgar Bergen.

1951, U.S. student slang, probably an alteration of 1940s slang nert "stupid or crazy person," itself an alteration of nut. The word turns up in a Dr. Seuss book from 1950 ("If I Ran the Zoo"), which may have contributed to its rise.
