Southwestern Bell Telephone Co. Building

🏛️The era

In the years after World War I, San Antonio was growing fast, and much of that growth pushed north of downtown. New residential neighborhoods such as Alta Vista, Beacon Hill and Laurel Heights filled with bungalows and young families. Those families wanted the conveniences of modern life, and the telephone was near the top of the list.

In the early 1920s the telephone was changing from a luxury into an everyday necessity, but every call still needed people to connect it. Neighborhood exchanges were the nerve centers of that system. Each one was a building full of switchboards, batteries and cables, staffed around the clock by operators who plugged one line into another by hand.

The automobile was arriving at the same time, but it had not taken over yet. The marker notes that most families were only just buying their first cars. A workplace within walking distance of home still mattered, and building an exchange in the middle of the neighborhoods it served made practical sense for the company and its workers.

The decades that followed brought a second revolution, this time in the air. After World War I, trained pilots and surplus aircraft went looking for peacetime work. Aerial photography grew from a battlefield tool into a business, and this building would become part of that story too.

👥People & events

The Woodlawn Exchange was announced as early as 1919, but it took four more years to open. Planning began under the Southwestern Telegraph and Telephone Company, and the property passed to the Southwestern Bell Telephone Company in 1920. At midnight on July 14, 1923, the switch was thrown. Thirty-five operators sat ready at their boards to connect the neighborhood's first calls.

The building was designed with its workers in mind as well as its machinery. Battery rooms and a cable vault kept the system running. Locker rooms and a cafeteria served the operators, most of whom were probably young women, as they usually were in that era. Next door was a grass tennis court, which hints at a company trying to make long shifts at the switchboard a little more pleasant.

In 1936 the building began a new chapter. It was sold to Tobin Aerial Surveys, the company founded by San Antonio native Edgar G. Tobin. Tobin had trained as a combat pilot in World War I and then put his flying skills to work in business. He produced some of the earliest aerial photographs made for commercial use: maps of oil leases, land and property ownership. His company grew into a fleet of planes flying out of San Antonio's Stinson Field.

During World War II, the company's headquarters here coordinated aerial mapping of large parts of the United States. In 1955 the building passed to the United Cerebral Palsy Association, which installed a hydraulic elevator and used the space to advocate for people with cerebral palsy and their families. UCP sold the building in 1963, and it became housing, which suits a building that was always meant to sit among homes.

🇺🇸Its place in the American story

Across the country in the 1920s, neighborhood exchanges like this one carried the telephone into ordinary homes. They also created one of the era's largest new sources of work for women. The Woodlawn Exchange is a local example of a national change: Americans were becoming a people who expected to reach one another instantly.

Tobin Aerial Surveys belongs to another American story, the move of aviation from war to commerce. Aerial photographs changed how land was bought, sold, drilled and mapped. That mattered a great deal in Texas, where oil and large landholdings made accurate maps valuable. In World War II, mapping from the air became a national need, and the work coordinated here fed into it.

The building's later uses tell a quieter story. A home for disability advocacy, and then residences, show how sturdy early twentieth-century buildings have been adapted again and again as American cities changed around them.

🧭If you visit

Look for a two-story building of red and brown brick in several tones. Its restrained Colonial Revival design includes stone trim at the cornice and around the entrance. The double-hung windows topped by transoms were practical in their day, letting light and air into rooms full of switchboards and operators before air conditioning was common.

The building is now residential, so enjoy it from the sidewalk and respect the privacy of the people who live there. Take a moment to picture the neighborhood around you in 1923, with operators walking to work along these streets and a tennis court on the grounds next door.

This stop fits well into a day exploring San Antonio's older north-side neighborhoods, where early twentieth-century homes still line the streets. For a companion stop, aviation fans can look into Stinson Field, the historic airfield where Tobin's fleet once flew.
