Was this term (I believe it is a synonym of geek, nerd, and so on) based on the television series Dexter or was it around before that and the series based its name on it?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
It's been around a lot longer than the TV series Dexter.
“nerdy intellectual,” by 1986, U.S. teenager slang, from the character Poindexter, introduced 1959 in the made-for-TV cartoon version of “Felix the Cat.”
The TV series is based on the novels by Jeff Lindsay:
One of the most interesting questions came from a librarian. She asked whether Dexter's name came from "dexterous", meaning left handed, and "sinister", meaning right handed. Lindsay was stunned, saying it was only the second time he's ever been asked this. She was correct - he said the book's original title was the "Left Hand of God".
Although dexter is really Latin for right and sinister is Latin for left. From TV Tropes (click "open/close all folders"):
Meaningful Name: In Latin Dexter means right and is the opposite of Left, which is Sinister. The main character must follow the Code of Harry so as to appear as Dexter and not let on that he is Sinister.
- Also, Dexter refers to dexterity. Defined by the Merriam-Webster dictionary as: "mental skill or quickness / readiness and grace in physical activity; especially : skill and ease in using the hands."
- Probably not intentional, but dextrose is a more scientific term for blood sugar [sic, blood sugar is glucose, not dextrose].
