Starting at the age of 15, John Greenewald, Jr. was struck with a curiosity that led off a lifelong journey. First researching the UFO phenomenon, Greenewald began utilizing the Freedom of Information Act (FOIA) to hammer the United States Government for answers, and he targeted every government agency to get them.

As he waited for answers on this niche of the paranormal, he then branched off to investigate nearly every government secret imaginable. He was a sophomore in high school when he first started his trek in 1996, and he archived all of his research on a website that became known around the world as The Black Vault. Today, he has amassed well more than 2,000,000 pages of declassified records.

His efforts throughout decades of research have been responsible for getting hundreds of thousands of pages that have never seen the light of day into the public domain. He has appeared on numerous television and radio programs throughout the world and is frequently sourced in various news articles and stories for his archive and his discoveries.
