BOB DEAN
Robert Orel Dean (March 2, 1929 – October 11, 2018) was an American ufologist from Tucson, Arizona.
Dean retired from the U.S. Army as a Command Sergeant Major after a 28-year career. He appeared on radio programs, TV documentaries and at conferences discussing the subject of UFOs and a government cover up of alien visitations to Earth. Dean claimed to have viewed a classified government document called “The Assessment” that discussed threats posed by alien activity on Earth, and concluded that no such threats existed. Dean said he considers himself a professional UFO researcher and had “cosmic top secret” clearance while in the military.
