There will be a few Big Names in town today.

Almost the entire Kennedy family will be on hand, with former members of the Kennedy administration, as Harvard's Graduate School of Public Administration becomes the John F. Kennedy School of Government, and the Institute of Politics is officially created.

A special dinner in Holyoke Center will mark the beginning of the School and the Institute. Among the guests will be Mrs. Joseph P. Kennedy, Jacqueline Kennedy, Sen. Robert F. Kennedy '48, Sen. Edward M. Kennedy '54, Sargent Shriver, Arthur M. Schlesinger Jr. '38, Theodore Sorensen, and McGeorge Bundy.

There will be about 80 guests at the exclusive dinner; others will include high officials of the University -- President Pusey and the members of the Corporation, some Faculty associates of the Institute of Politics, and the Institute's fellows.

This afternoon the Institute's advisory committee will meet for the first time. The most important announcement expected to come out of the meeting will be the names of the honorary associates of the Institute. This group, made up of high government officials who will spend several days in Cambridge, is expected to include several cabinet officers.
