Help needed to identify 1940s Stackpole workers

Mary Malone knew she had a project on her hands, but as a director of the Historical Society of St. Marys and Benzinger Township, she was used to that. What she didn’t know was that it would take her two years and counting, and lead her to discovering more about her own family history.“I was at a historical society meeting, and afterwards I was going through one of the books on the shelves, and it was an Airco Carbon book—Speer Carbon—and I found my dad’s picture in there, and I got so excited because it was before I was even born,” Malone said.
