President John Quincy Adams (1843)
According to History, President John Quincy Adams was farsighted but underrated” and “the first president not to have been a founding father.” On top of that, he was “[t]he first son of a president to be elected,” and “[t]he first to marry a woman born outside the United States.” Even though he was not the first sitting POTUS to have his portrait taken, he is the earliest one to be photographed. It was shot by Philip Haas in 1843. Sadly, there is not a lot of information known about when the photo was taken.
President John Tyler (c. 1845)
After President William Henry Harrison died a month into his term, John Tyler succeeded him as the Vice President. He made history as the first Vice-President to do so! This was also the reason his critics called him “His Accidency.” In general, presidential historians do not rank the Tyler administration highly. At the moment, he is survived by a single grandchild by the name of Harrison Ruffin Tyler.
