1st photograph of a president in office

With this being the Month of Photography here in Denver, I was wondering who was the first president to be photographed rather than only painted. It was William Henry Harrison, our 9th president. This image was captured by daguerreotype in 1841. He passed away at age 68 due to complications from pneumonia, after serving only 31 days in office. The shortest term ever served. (He was the grandfather of our 23rd president, Benjamin Harrison, who was president from 1889 to 1893.) William Harrison and John Tyler were nominated by the Whig Party for the 1840 election. Harrison earned the nickname Old Tippecanoe for an 1811 indian battle he fought in, prompting the election slogan and song: "Tippecanoe and Tyler too" He was the last president born as a British subject.
