Stanley H. Hoffmann, professor of Government, led a group of about 15 Harvard students to Washington last Friday afternoon for a secret meeting with Henry A. Kissinger, President Nixon's national security advisor.

The three students thus far identified as members of the group refused to discuss the session, saying that silence was a condition of their meeting. Hoffmann last night also declined to comment.

"Kissinger was very explicit that we couldn't attribute statements to him. That was the arrangement under which we could see him," Stephen J. Ellmann '72, one of the students, said last night.

The students-Ellmann, Donald J. Gogel '71 and Rebecca J. Scott '71-are all Social Studies concentrators. Hoffmann is a former head of the Social Studies department and is now on the department's degree-granting committee.

Kissinger is presently on leave from Harvard to serve in the Administration's top foreign policy post. Before his departure from Cambridge in early 1969, he was professor of Government and a member of the executive committee of the Center for International Affairs.
