With a gust of wind and a definite air of super-sophistication, Jacqueline Onassis swept into the Harvard Faculty Club at 7 p.m. last night, joining the other members of the Institute of Politics Advisory Committee.

Onassis, dressed in a black-on-white pantsuit and wearing her "Jackie" smile, did not acknowledge anyone, as onlookers commented on how "amazing" looking she was.

The advisory committee met last night and will meet again this morning with selected Kennedy School of Government faculty, the Institute of Politics staff and members of the institute's student advisory committee, Jonathan Moore, director of the Institute of Politics, said yesterday.

Topics of discussion include recent developments and current-year plans at the Kennedy School and the Institute of Politics, Moore said.

Moore compared the annual meetings to a "family gathering" of the institute and the committee, established simultaneously in 1966.

Onassis, Senator Edward M. Kennedy '54, Robert S. McNamara, Lord Harlech, Senator John C. Culver, George C. Lodge '50, Professor of Business Administration, and Vernon E. Jordon Jr. were among the "family" members at the Faculty Club last night.

"The fact that the members came shows their concern," Lois H. Tendler '77, member of the institute's student advisory committee, said before climbing the plushcarpeted stairs and entering the room for cocktails.
