John Greenewald Jr. is the founder of The Black Vault, a large online archive built through decades of Freedom of Information Act requests.
ResearcherJohn Greenewald Jr. is an American researcher who began filing Freedom of Information Act requests as a teenager and created The Black Vault to publish the results. The archive contains millions of pages spanning military, intelligence, nuclear, paranormal, and UFO subjects, organized so readers can inspect the underlying government records.
Greenewald began filing records requests as a teenager and gradually turned the results into The Black Vault, a searchable archive spanning intelligence, defense, nuclear history, paranormal programs, and UFO investigations. The project required persistence through delays, denials, appeals, fee disputes, and heavily redacted releases. Over decades, that administrative work became a distinctive professional identity. He is known not for one revelation but for repeatedly forcing agencies to state what records they hold and what legal reason they give for withholding them.
Greenewald has become one of the most persistent document-focused voices in UAP research. He requests case files, emails, videos, program records, and administrative correspondence, then analyzes what agencies released, withheld, transferred, or said did not exist. He is often critical of both Pentagon messaging and disclosure claims that outrun the documentary record. His conclusions may be debated, but the source files he publishes give others material to check.
Greenewald is central to FOIA and transparency. He demonstrates that bureaucratic details—routing slips, exemptions, retention schedules, and contradictory searches—can be as important as a dramatic video. He is not an official custodian of the records and cannot force agencies to release classified material. His role is to build a public paper trail around UAP and to make government claims answerable to their own documents.

RT @TheUfoJoe: My favorite Greenewald critique of me. #ufotwitter I DO believe in Bob lazar. I do, I do, I do! I've seen him in person. H…
I thought this could be it and the public saw the "Estimate of the Situation" document from 1948 that concluded UFOs were interplanetary/extraterrestrial. The document, with the same title and year as the rumored goldmine for UFO history buffs, was slated to be released per a few references I've seen in the past. Excited to see the document was finally added to NARA's UFO site. Problem? It has nothing to do with what has been rumored for decades. I feel we are getting punked on so many levels...

YouTube vids and talks start back up this week. For those who care, what do you want to hear about most?
Yes. And thank you for asking. My family comes first, so as a result, so does my job to take care of them :) But, I realized some other stuff was going on, too. This week - I’ll return to it with some much needed explanations for those who care to listen… https://t.co/BZNFooS1ms [Quoted] @theblackvault any plans to keep doing audio podcasts? Haven’t seen anything new in Apple for a while
If he actually did, and he’s openly talking about them, then they are not classified. I think everybody should agree with that. Now, with that said, he should name exactly where we all can find the report, and get it released to the general public. https://t.co/QLFoswkQgu [Quoted] 🚨 Eric Davis just revealed where recovered alien bodies were taken. The location: the Army Medical Museum, later known as the Armed Forces Institute of Pathology, in Washington, D.C. He says he has seen the records...
