Honorable Charles H. Percy
United States Senate
Washington, D. C. 20510
1 2 SEP 1977
Dear Senator Percy:
This responds to your note of Au ust 15, 1977 forwarding a
letter from which requested information
regarding certain tests he believes may have been performed on him.
The recently discovered files of Project MKULTRA do contain
evidence that research involving human testing was conducted in
the fields of behavior control using techniques involving hypnosis,
drugs, etc. Our records indicate such testing on unwitting subjects
ceased in 1963. Unfortunately, neither Project MKULTRA files
nor any other files thus far located contain the names of persons
who may have been used as subjects. Therefore, in our search of
relevant files name was not found.
Admiral Turner has assured the Congress that the CIA will
attempt to identify those persons who were the subjects of unwitting
testing conducted under Project MKULTRA. To this end, the insti-
tutions where Project MKULTRA testing took place have been notified
of their involvement with the project. Admiral Turner has offered
these institutions his full cooperation in helping them identify the
persons who were test subjects. Please be assured I will inform
you immediately if any institution notifies CIA that it has identified
I las having been a Project MKULTRA test subject.
Per your request, I am returning the letter from
to you.
Sincerely,
George L. Cary
Legislative Counsel
