David Rice Atchison is sometimes refered to as "President for a day." He was president pro tempore of the Senate when James Polk's presidential term expired (March 4, 1849). Polk's successor, Zachary Taylor, refused to take the oath of office on a Sunday for religious reasons. Since Taylor's vice president (Milllard Fillmore) also hadn't taken his oath of office, some claim this would make Atchison next in line for the post of President and, thus, acting president.
It's worth noting, however, that Atchison took no oath of office as president either. If he was able to be considered president without an oath, then one would think that Taylor would also be able to be president without the oath. Also, the Senate had adjurned on March 3rd, so technically Atchison's term as president pro tempore had also expired. Finally, Atchison took no presidential actions and, according to stories, sequestered himself and refused all contact during the day he was supposedly president.
David Atchison never claimed to be president, either at the time or later in his life and his proported presidency was not and is not recognized by any governmental body.
In summary, the short answer is "no one," the longer answer is "no one, but David Atchison is sometimes refered to in that way."
