Chester Alan Arthur (October 5, 1829 – November 18, 1886) served as U.S. President number 21 from 1881 to 1885. He was never elected to any public office, moving into the Top Dog post after James Garfield was assassinated, six months into the job. It appears that he didn't like the position all that much, in that he mounted a very lackluster campaign in the 1884 election.The dude had some amazing facial hair. I couldn't find any instance where he and Ambrose Burnside (to whom the term 'sideburns' is supposedly attributed) ever met during their stints as generals during the Civil War, but they both sported some crazy cheek fuzz.
He did, however, earn some accolades. Mark Twain once wrote, "[I]t would be hard indeed to better President Arthur's administration." Or should that be taken as a back-handed compliment?
