In his 1986 biography of Emperor Norton, William Drury leaned heavily into anecdotal stories forging an association between the Emperor and Martin & Horton’s, a saloon at the southeast corner of Montgomery and Clay Streets, San Francisco, that was known as a hub for editors and reporters — and also for having one of the better free-lunch counters.

But, it turns out that, in addition to Martin & Horton’s, the building on this corner — which was directly across Clay Street from where the Transamerica pyramid now stands — housed a second saloon — a spot that also was known for its good food and drink, and for catering to the journalists and writers who covered the Emperor in their papers.

Which begs the question: Was Emperor Norton a regular at one saloon? — the other? — or both?

Jumping off from a well-known photograph of the Montgomery and Clay building after it suffered a fire in November 1862, the following research documents in some detail the overlapping histories of these two saloons and their proprietors — whose businesses had space in two different buildings on this corner between 1854 and 1887.

It’s a fascinating story.
