Update: The architect was George I. Barnett, who was one of the earliest professionals of his field in St. Louis. I wrote an article about him in St. Louis Magazine. There have been serious structural failures on the west side of the building as of November of 2021. I revisited the building in June of 2023. Destroyed by fire on the night of September 14, 2023.
Stabilized after the ferocious storms that ripped one side of the building off, the Mullanphy Emigrant Home sits awaiting a new use for a new century.
