the first gas station that was designed to sell gas was at the intersection of Baum Boulevard and St. Clair Street in East Liberty, Pittsburgh

Baum Boulevard was -- and in many ways still is -- Pittsburgh's "automobile row," and Gulf Oil's headquarters was in Pittsburgh. The oil industry had a long history in the area as it is not far from Titusville, site of one of the country's first oil wells and home to a large oil rush in the 1850s and 1860s.

And Baum Boulevard had been dedicated as part of the Lincoln Highway on Oct. 31 of that year, Mr. Butko said.

"It made total sense for Gulf to open the first station there," he said.
