How this list should grow

City directories, payroll fragments, union records, and labeled sales photos can add clerks, roasters, drivers, and agents—the social history of the plant, not only the officer line. When you have a primary source for someone new, they can be added here and, where appropriate, spun into a blog post or timeline entry.
