Some years ago, I happened upon a lengthy newspaper article — from the 1890s, if memory serves — with a list of honorarily named California redwoods. One of the trees carried the name “Emperor Norton” — so, I made a mental note and resolved to return to this “detective ground” in the future.

Recently, I was delighted to find photographic evidence of an “Emperor Norton” tree: an apparently unpublished stereocard by Eadweard Muybridge, dated 1868, showing a man in a deep bow before a redwood with an "Emperor Norton" sign affixed to it. 

The Bancroft Library, which has the card, identifies the site of Muybridge's scene as "Probably in the Mariposa Grove, near Yosemite Valley."

In my effort to confirm this detail, I found multiple references — from the period between 1867 and 1910 — to "Emperor Norton" trees in both of the noted redwood sections of Yosemite: the one in Mariposa County and another in Calaveras County.

The evidence strongly suggests that the tree in Muybridge's stereograph is in Calaveras.
