South Bend Watch Company Factory

Note that the factory was long and narrow with lots of windows. Though the building was wired for electricity, it was often unreliable. The windows provided natural light for workers when the electricity failed.

Here is a pic of a worker in the factory with their bench right up against the window. Note the light pouring in.

I don't know the original source of this photo. This is a scan of a reprint I bought on eBay.
