Samuel Mackenzie Elliott[1] (1811–1875) was a Scottish-American medical doctor, pioneer of American ophthalmology, abolitionist leader, and a Union soldier who served as lieutenant colonel of the 79th New York Volunteer Infantry.[2]
^note spelling of middle name, as in his published work on the Highland Brigade and his 1875 New York Times obituary, is "'Mackenzie", not "MacKenzie", as the official name of the Dr. Samuel MacKenzie Elliott House.
