Tesla said it in a press interview with the radio writer Orrin E. Dunlap Jr., published in The New York Times on 8 April 1934 under the headline “An Inventor’s Seasoned Ideas: Nikola Tesla, Pointing to ‘Grievous Errors’ of the Past” (page X9). Quote Investigator ↗ traced the line to that article and credits Tesla, and the full interview text reproduced at Tesla Universe ↗ contains the sentence word for word.
“Be alone, that is the secret of invention; be alone, that is when ideas are born” Nikola Tesla, interviewed by Orrin E. Dunlap Jr., "An Inventor's Seasoned Ideas," The New York Times, April 8, 1934, p. X9.

Spoken remark, quoted in a press interview
It is providential that the youth or man of inventive mind is not “blessed” with a million dollars. He would find it difficult to think. The mind is sharper and keener in seclusion and uninterrupted solitude. No big laboratory is needed in which to think. Originality thrives in seclusion free of outside influences beating upon us to cripple the creative mind. Be alone, that is the secret of invention; be alone, that is when ideas are born.One paragraph of a longer interview
Dunlap breaks the quoted speech with the reporter’s attribution — “said Mr. Tesla” — after the first sentence; the words are Tesla’s throughout. The interview itself is mostly about radio, television and the wireless transmission of power.
8 April 1934 — Tesla, interviewed high above the New York sidewalks by the Times’s radio writer Orrin E. Dunlap Jr., speaks the sentence inside a paragraph about inventors and money. The article text is reproduced in full at Tesla Universe ↗.
The anchor finding — Quote Investigator ↗ pins the quotation to that article (page X9, cols. 1–2) and concludes that Tesla should receive credit for the comments he made about the value of solitude in the 1934 interview.
Corroboration — Wikiquote ↗ carries the same passage among its sourced Tesla quotes, citing “An Inventor’s Seasoned Ideas,” The New York Times, 8 April 1934 — not as disputed or misattributed.
Reprints — per Quote Investigator’s reference list ↗, the passage recurs in Thomas P. Hughes’s American Genesis (1989, page 25) and David Wallechinsky’s Twentieth Century: History With the Boring Parts Left Out (1996, page 574), sometimes with sentences omitted.
Tesla’s own books and articles from 1919 and earlier are public domain, but this line is not from them: its only documented publication is a New York Times article of 8 April 1934, which postdates the 1931 US public-domain cutoff. Quotle.info therefore treats the passage as in-copyright to the newspaper and its writer, and quotes only the short paragraph under examination.

Fact-check
The sourcing problem
Unusually for a Tesla quote, the attribution is sound. What goes wrong is the paperwork — and the trimming.
✕
Citation“Nikola Tesla” with no source at all unsourced
For years the line travelled as a bare aphorism with the newspaper original missing from the chain; Quote Investigator ↗ opened its inquiry because a reader asked for help locating any citation for it.
✕
WordingAbridged reprints sentences dropped
Quote Investigator notes that “in later years the interview text was reprinted with some sentences omitted” — which is why the closing sentence usually appears without the four that lead up to it. See the trail ↗

MeaningMotivational-poster framing context lost
Detached, it reads as generic advice to work alone. In Dunlap’s text the paragraph begins with Tesla arguing that it is providential an inventive young man is not “blessed” with a million dollars — his point is that seclusion, not a big laboratory, is what keeps a mind sharp. Read the paragraph ↗

Context
Why he said it
The line is not a standalone motto. It sits inside a paragraph about money: Tesla opens by calling it providential that a young man of inventive mind is not “blessed” with a million dollars, because he would then find it difficult to think. Solitude, in his telling, is the compensation of the poor inventor — no big laboratory is needed, and originality survives better without “outside influences beating upon us.”
Dunlap’s interview was mainly about radio, television and the wireless transmission of power, conducted in Tesla’s room high above the New York sidewalks; the remark on being alone is a digression within it. Read in that setting it is closer to a defence of how Tesla himself had worked — and of his own straitened circumstances in the 1930s — than to general advice about creativity.
No big laboratory is needed in which to think.
How the passage travelled
Quote Investigator records that “in later years the interview text was reprinted with some sentences omitted,” which is how the closing sentence came loose from the four that explain it.
The passage reappears in Thomas P. Hughes’s American Genesis (1989) at page 25 and in David Wallechinsky’s Twentieth Century: History With the Boring Parts Left Out (1996) at page 574, according to Quote Investigator’s reference list ↗ — and, more recently, in newspaper features about creative work.

Tesla’s work on the rotating magnetic field made the practical alternating-current motor possible, and he had described a system for the wireless transmission of energy by 1892. By the 1930s, when he gave this interview, most of his patents had expired and he was — in Wikipedia’s summary of his final years — effectively bankrupt, living in a succession of New York hotels while still granting interviews about radio, power and the future. The remark about solitude belongs to that late period: an old inventor explaining, with some self-interest, why having no money and no laboratory need not stop anyone from thinking.
