[Justus E. Moore and Captain Ward] received official permission to set up their daguerreian apparatus in the Capitol, including in the private chambers of Vice President Johnson and in the chamber of the Senate Committee on Military Affairs. In early March, Moore wrote that he and Ward had "taken many likenesses of the most distinguished members of the Senate and the House of Representatives." Even newly elected President William Henry Harrison sat for Moore and Ward in early March; their portrait of Harrison is thought to have been the first ever taken of a president, and probably was the last portrait taken of him before his death in April 1841.
