Around 1912 the Pacific Telephone and Telegraph Company produced three photo books.
These books are scanned from our museum library. They are described as “Inventory of Exchange Telephone Plant, San Francisco, California, as at December 31, 1912.”
We only have books 13, 14 and 15 (in Roman numerals) in our collection.
If someone knows more about books 1 – 12 please let us know in the comment section below.
According to the text in the first photo book, most of these photographs were taken at various times during the six months prior to May 1, 1914, though some are much older.
The photographs are divided into several subjects:
- Pole Line Construction
- Aerial Cable Construction
- Aerial Wire Construction
- Underground Conduit Construction
- Underground Cable Construction
- Central Office Equipment
- Subscriber Stations
- General Equipment
Photos like the 333 Grant Ave. photo above are a fun example of comparing some of these old photos with today’s situation.
We may be adding more of these comparison photos in the future.

I worked at 333 Grant in the early ’90s.
Great old building.
Recognized a few of the other S.F. C.O. s from their pictures
I’m glad you enjoyed it!
I had “fun” scanning it all and making it available online.
the books are really cool! What a job providing telephone service for San Francisco, even in 1912!
