Chief Justice Tenures
A side note to the confirmation of John Roberts, Jr. as Chief Justice of the United States: rather interesting how few Chief Justices there have been in American history, considering that the post has existed since John Jay first took it in 1789.Roberts is only the 17th man to hold the post (if you toss out William Cushing, who either took the job for a few days and then resigned, or turned it down altogether, in 1796). Wikipedia has a good clear list.
