the man who was president for a day
David Rice Atchison David Rice Atchison (August 11, 1807 – January 26, 1886) was a mid-19th century Democratic[1] United States Senator from Missouri.[1] He served as President pro tempore of the United States Senate for six years.[2] Atchison served as a major general in the Missouri State Militia in 1838 during Missouri's Mormon War and as a Confederate brigadier general during the American Civil War under Major General Sterling Price in the Missouri Home Guard. He is best known for the questionable claim that for one day (March 4, 1849) he may have been Acting President of the United States.[3] This belief, however, is dismissed by nearly all historians, scholars, and biographers.[4][5]
