Which Nikola Tesla quotes are real?
8 of these 15 are real
Only the ones you can trace to something Tesla wrote or said on the record, like “Be alone, that is the secret of invention; be alone, that is when ideas are born,” from The New York Times in 1934. Many of the most famous have no source at all, including “think in terms of energy, frequency and vibration” and the 3, 6, 9 “key to the universe.” Test yourself on 15 below, then see the source for every one.

How to tell a real Tesla quote from a fake
1. Ask for the date and the paper
A real quote comes with a place and a year: the June 1900 Century Magazine, the January 30, 1926 issue of Collier’s, The New York Times on April 8, 1934. If a quote only ever appears on an image with his face, it has no source yet.
2. Search his own words
Most of what Tesla published is free online. His autobiography, My Inventions, is on Wikisource, and you can search every word of it on our quote page. Twenty-First Century Books keeps 61 of his papers, articles and interviews in one place. Paste in a distinctive phrase. If it is not there, be suspicious.
3. Check the lists that already did the work
Wikiquote’s page on Tesla separates sourced quotes from disputed ones, and its talk page keeps a list of unsourced lines. Fact checkers like Snopes and AAP FactCheck have traced several viral ones to a Facebook post, a 1995 play and a man selling a product.
4. Watch for the words he did not use
Tesla wrote like an engineer of his time: long sentences, formal words, specific machines. Modern wellness words, “vibration” as a mood, “energy” as a feeling, “the universe” as a helper, are a warning sign. They belong to the 21st century, not to 1900.

Questions
Tesla quotes
Which Nikola Tesla quotes are real?
Real ones can be traced to something Tesla wrote or said on the record. Examples: “Be alone, that is the secret of invention; be alone, that is when ideas are born” (The New York Times, 1934), “Our virtues and our failings are inseparable, like force and matter” (Century Magazine, 1900), and his 1926 prediction in Collier’s that wireless would turn the whole earth into “a huge brain.”
Did Tesla say “think in terms of energy, frequency and vibration”?
There is no good evidence he did. The only origin is Ralph Bergstresser, who sold a product called Tesla Purple Plates and claimed decades later that Tesla said it to him in 1942. Wikiquote lists it as disputed, and it is not in his published writings.
Did Tesla say “the present is theirs; the future is mine”?
Yes, in a 1927 interview with the Belgrade newspaper Politika, while talking about his rivals Pupin and Marconi. The famous English version is a translation. The full line reads “The present is theirs; the future, for which I really worked, is mine.”
Did Tesla predict the smartphone?
In a 1926 interview with Collier’s magazine he said wireless would let people communicate instantly over any distance, with an instrument a man could carry in his vest pocket. Snopes rates the quote a correct attribution.
Did Tesla say “man-made horrors beyond your comprehension”?
It is unproven. The line first appears in Esquire in October 1947, four years after he died, with no source, and Snopes found the evidence too thin to rate.
Did Tesla say 3, 6 and 9 are the key to the universe?
No source has ever been found. The line is not in his writings, patents or interviews, and the earliest trace is an online comment from around 2010.
