Allan Dulles - first director
John Foster Dulles - Eisenhower's Secretary of State
Maternal grandfather, John W. Foster, was Secretary of State under Benjamin Harrison
Uncle by marriage, Robert Lansing was Secretary of State under Woodrow Wilson
Dulles was uncle to Avery Dulles, a Jesuit priest and cardinal of the Catholic Church, who taught theology at Fordham University
Supreme Court Justice Arthur Goldberg once stated that "The Dulles brothers were traitors." Some historians believe that Allen Dulles became head of the newly formed CIA in large part to cover up his treasonous behavior and that of his clients.
Which leads to the Bushes…
Just before his death, James Jesus Angleton, the legendary chief of counterintelligence at the Central Intelligence Agency, was a bitter man. He felt betrayed by the people he had worked for all his life. In the end, he had come to realize that they were never really interested in American ideals of "freedom" and "democracy." They really only wanted "absolute power."
Angleton told author Joseph Trento that the reason he had gotten the counterintelligence job in the first place was by agreeing not to submit "sixty of Allen Dulles' closest friends" to a polygraph test concerning their business deals with the Nazis. In his end-of-life despair, Angleton assumed that he would see all his old companions again "in hell."
