This is a picture of a building in the marshes down at the south end of the San Francisco Bay. This horrible looking building was used exclusively for the development of tetraethyl lead which was used in gasoline and now more or less banned because of its noxious qualities and air pollution properties. But it revolutionized the power of combustion of gasoline. The outside of the building was corrugated iron or asbestos board. The interior frame was built of huge redwoods, either 8'x8' or 12'x12'. The chemicals were so corrosive that the tough redwood was just kind of peeling in long shreds from exposure to the fumes and moisture. I don't know how my camera ever stood it for the half day I was in there." -Roger Sturtevant interview conducted by Joyce Minick
