As it happens, p. 99 of my book History's Shadow: Native Americans and Historical Consciousness in the Nineteenth Century features one of the earliest known American daguerrotypes, a spectral portrait of Stephen DuPonceau.

In studying Native American languages, customs, archaeological remains etc these intellectuals tried to figure just who these people were, where they had come from and when. In so doing they shaped a distinctively American historical consciousness and by the end of the century had created a division between Euro-American, who had a history, and Native Americans who did not.
