William R. King

William Rufus deVane King (April 7, 1786 – April 18, 1853) was a U.S. representative from North Carolina, a senator from Alabama, and the thirteenth vice president of the United States. Excluding John Tyler and Andrew Johnson — both of whom ascended to the presidency — he was the shortest-serving person to occupy that office (45 days, "see List of vice presidents of the United States by time in office").
