More about vice-presidents:
The office of the vice-president has been vacant more than a dozen times. Eight men have succeeded to the presidency after the death of the president.
Some would say that one of the most unfortunate vice presidents was William Rufus King. In 1852, King was elected vice-president under President Franklin Pierce. Given the oath of office in Havana, Cuba, he was the first man to take the oath on foreign soil.
He died in 1853 before Congress had actually convened, and did not serve officially as vice-president. He was also the first vice-president of America who had served in both the House of Representatives and the Senate.
