President Reagan on Friday named Howard H. Baker Jr., former senator and White House chief of staff, to the Foreign Intelligence Advisory Board for a two-year term.

Baker served as both majority leader and minority leader during his Senate career and was White House chief of staff for 16 months before his recent resignation. He will succeed Albert D. Wheelon on the board.Although Reagan leaves office in little more than six months, some of his appointments to government boards extend into his successor's administration.
