William Milton Cooper (May 6, 1943 - November 5, 2001) was an American writer, shortwave broadcaster, militia supporter and conspiracy theorist.

Cooper’s earliest notoriety developed among UFO enthusiasts, as he promoted a variety of conspiracy theories regarding UFOs, Area 51, the Kennedy Assassination, and much more. In the late 1980s and early 1990s, Cooper claimed that John F. Kennedy was shot by the limosine’s chauffeur, using bullets filled with blowfish poison.

Cooper is perhaps best known for his book Behold A Pale Horse, which details many of his claims about various conspiracy theories. The title is a quote from The Book of Revelation in the New Testament. The book includes the text of The Protocols of the Learned Elders of Zion, a famous anti-Semitic hoax document.

An outspoken critic of what he considered US government abuses, Cooper was charged with various crimes, including tax evasion from 1992 to 1994, and bank fraud for giving false information on a loan application.

Cooper reportedly met with Timothy McVeigh, who sought Cooper’s advice or support. When McVeigh refused to offer details of his plans, Cooper dismissed him.

On November 5 2001, Cooper was shot and killed by Apache County, Arizona Sheriff officers who were serving an arrest warrant after Cooper reportedly threatened passersby near his home in Eagar, Arizona. Cooper was 58 years old.

Mystery Babylon is the title of a series of shortwave radio broadcasts made by former naval intelligence officer and author Milton William Cooper, which originally aired on his show The Hour of the Time, on WWCR in 1993-94. The title refers to mystery religions, and the Biblical figure the Whore of Babylon. The series is the culmination of over 30 years of research into the history of the Mystery Schools, Freemasonry, and the New World Order. The series consists of 42 audio tapes and 1 video tape.

Over the course of the series, Cooper gives an extensive background of the occult history and origins of secret societies throughout history and up to the present day. Starting with the dawn of man, Cooper brings the listener through the Egyptian mystery religion of Isis and Osiris and on to the beginnings of the secret society networks from the Assassins to the Freemasons and on to the Nazis, and explains how their belief in ancient wisdom and rituals is preserved and practiced by various social, religious, and political groups, such as the Freemasons, the Skull and Bones, and Rosicruscians, to this day.
