History
William Westerfeld, a German-born confectioner, arrived in San Francisco in the 1870s. By the 1880s, he had established a chain of bakeries. He hired local architect Henry Geilfuss to design for his family of six a 28-room mansion with an adjoining rose garden and carriage house. The house was constructed in 1889 at a cost of $9,985 (equivalent to $357,800 in 2025).
When Westerfeld died in 1895, the home was sold to John Mahony, of Mahony Brothers, noted for building the St. Francis Hotel and the Palace Hotel after the 1906 earthquake. Mahony replaced the rose garden with flats to meet the city's dire need for housing.
In 1928, a group of Czarist Russians bought the home.
This brief starts where responsible research should: with the source description of “William Westerfeld House” as place in California listed on National Register of Historic Places. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as place in California listed on National Register of Historic Places. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q8020221. Authority coordinates are 37.777, -122.436. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1198, 1889, 2025 and 1895.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
