In the 1990s, psychologist D. Corydon Hammond publicized a detailed theory of ritual abuse drawn from hypnotherapy sessions with his patients, alleging they were victims of a worldwide conspiracy of organized, secretive clandestine cells who used torture, mind control and ritual abuse to create alternate personalities that could be "activated" with code words; the victims were allegedly trained as assassins, prostitutes, drug traffickers, and child sex workers (to create child pornography). Hammond claimed his patients had revealed the conspiracy was masterminded by a Jewish doctor in Nazi Germany, but who now worked for the Central Intelligence Agency with a goal of worldwide domination by a Satanic cult. The cult was allegedly composed of respectable, powerful members of society who used the funds generated to further their agenda. Missing memories among the victims and absence of evidence was cited as evidence of the power and effectiveness of this cult in furthering its agenda. Hammond's claims gained considerable attention, due in part to his prominence in the field of hypnosis and psychotherapy.
