[7] The property for the Spreckels Mansion was bought by Adolph as a Christmas gift for his wife Alma; they had been living in Sausalito.

[2] To build the mansion they combined several prime lots, and eight Victorian homes were moved to Jackson and Washington Streets.

[2] On this same trip Alma met with Auguste Rodin and brought 13 of his bronze sculptures to San Francisco for the 1915 Panama Pacific International Exposition, which later inspired the creation of the California Palace of the Legion of Honor.

[11] Steel added a very tall hedge in front of the mansion blocking the architecture, for the sake of privacy.

[10][11] The exteriors have been used for a few movies set in San Francisco; most extensively as the eponymous nightclub for the 1957 musical Pal Joey.
