In 1996, John Greenewald, Jr. began researching the secret inner workings of the U.S. Government at the young age of fifteen. With targets like the CIA, FBI, Pentagon, Air Force, Army, Navy, NSA, DIA, and countless others Greenewald utilized the Freedom of Information Act (FOIA) to gain access to thousands of records.

With a pile of documents on the topics of UFOs, the JFK Assassination, chemical/biological/nuclear weapons, top secret aircraft and more, Greenewald began scanning the documents to the internet for the world to access.

In time, this online archive, known globally as The Black Vault, has grown into the largest private online collection anywhere in the world, totaling more than 460,000 pages.

John Greenewald has been featured on television networks such as The History Channel, Discovery Channel, The Learning Channel, A&E, FOX, NBC, along with international networks such as the BBC (UK) and NTV (Russia).

In published media, Greenewald has been featured and quoted in more than one hundred articles, in papers such the Los Angeles Times, the Los Angeles Daily News, the Baltimore Sun, and featured on the front page of Yahoo! as one of the top stories for the day.

In broadcast radio, Greenewald has been featured on stations worldwide, including Coast to Coast AM (Premier Radio Network - syndicated), the Adam Carolla Show (CBS Radio - syndicated), the Bob & Sheri show (Greater Media Radio syndicated), and many others.

At the age of twenty-one, Greenewald published his first book Beyond UFO Secrecy in 2002. This book has recently been put into a second expanded edition, and re-published by Galde Press in January, 2008.

Today, his path towards creating The Black Vault led him to a career in television production, as a supervising producer, writer, director and editor. Currently working at Weller/Grossman Productions in North Hollywood, California, his many shows can be seen on The History Channel, National Geographic Channel, and Discovery Channel to name a few.
