In the spring of 958, Justice Harold Burton informed President Eisenhower of his decision to retire at the end of the Term, but, at the President's request, withheld public announcement until the latter was ready to name a successor. In September, Eisenhower appointed Potter Stewart, who became, at age forty-three, the second youngest person to serve on the Supreme Court since the Civil War.
