When a C.I.A. Director Had Scores of Affairs - NYTimes.com: Dulles’s behavior was well known in Washington and elsewhere, but never publicly reported. By the journalistic codes of the 1950s, it was not newsworthy.
The same code applied to Dulles’s superiors. Presidents Eisenhower and John F. Kennedy entrusted the security of the United States to him. What Dulles did in his private life, even when it intersected with his public role, was considered none of their business.
Allen Dulles, who died in 1969, may have been, as one biographer claimed, “the greatest intelligence officer who ever lived.” Yet by today’s standards, this master spy would not have been allowed even to join the C.I.A., much less lead it.
