The first photograph of a sitting United States president was taken of William Henry Harrison on March 4, 1841. The new executive had just delivered his inaugural speech — the outdoor address now most remembered (wrongly) for giving him the pneumonia that would kill him — and he paused, afterward, to pose for a portrait using the new technology of the daguerrotype.
That photograph, much like its subject, had an unexpectedly short tenure. Harrison’s inaugural portrait has since been lost to history — meaning that the oldest surviving photograph we have of an American president depicts a chief executive after his presidency.
