As far as I know, my father was the first American ever allowed to attend Moscow State University. I know he was offered a position with the CIA around that time because I remember eavesdropping on a conversation my mother and he had about then. She was adamantly against it and he didn't take it.
Why we were there in 1969 was that my father worked as a guide on an exhibit sponsored by the State Department. It's the "Education USA" exhibit listed for 1969-1970 here: http://www.state.gov.../ci/rs/c26473.htm
We didn't stay for the second half because of my mother. My dad had actually arranged for me to continue on with another guide, but my mother would not tolerate that. My brother and I both wanted to stay. We actually cried when we were told we had to go back to America.
