Lincoln's assassination in 1865 prompted countless memorial projects. In 1867 the Commonwealth authorized the acquisition of a bust of the late president from sculptor Sarah Fisher Ames, of Washington, D.C. Classically trained, Ames was a nurse and in charge of the hospital at the U. S. Capitol during the war. There she met the president on several occasions, and in 1862 modeled a portrait bust of him. This was originally installed in one of the niches that was created during the early remodeling of Doric Hall, and was later moved to the Senate Chamber.
