Summary for 4415 CALIFORNIA AVE / Parcel ID 790470-0100 / Inv # 0

Historic Name: PT&T Telephone Exchange Common Name: Centurylink
Style: Beaux Arts - Neoclassical Neighborhood: West Seattle Junction
Built By: Year Built: 1920
 
Significance

This building, constructed in 1920, is associated with early development of the West Seattle Junction.  The original building, a simple brick-clad structure, is largely intact, but there is a large addition on the north end. The building is still in use by Centurylink as a telephone equipment building.

This is a typical example of the telephone switching centers constructed in Seattle neighborhoods in the 1920s; similar buildings are located in Queen Anne, Wallingford and the Rainier Valley. It was built in 1920 by the Pacific Telephone and Telegraph Company (PT&T) and initially housed both telephone switching equipment and operators to put calls through. However, in 1923, the dial system came into use in West Seattle, eliminating the need for operators for local calls. Based on information on similar facilities, this building was probably built to a standard design by the Office of the Chief Engineer in PT&T’s San Francisco office.

PT&T was the predecessor to the Pacific Northwest Bell Company, a subsidiary of American Telephone and Telegraph Company (AT&T), which evolved to become Pacific Telesis and US West, now Qwest. Pacific Telephone Company was an early California-based telephone and telegraph communication company that gradually acquired numerous smaller telephone companies along the Pacific Coast, such as the local Sunset Telephone Company, which they acquired in 1917.  AT&T had been formed to provide long distance service, but in 1899 it became the parent company of the Bell System, which included Western Electric (manufacturing), Bell Laboratories (research and development), AT&T Long Lines and the regional Bell operating companies.  In 1984 the system broke up into eight companies by agreement between AT&T and the U.S. Department of Justice. The regional company, Pacific Northwest Bell, became Centurylink, which bought Qwest in 2011.
