My maternal grandmother, whom we called Nana, worked as a telephone operator for years. She was affected by the technological development of Ma Bell. First, she worked locally. Then, she had to travel to the next town for work. Finally, over her time with the one-time monopoly, she ended up commuting quite a distance from Sunapee, New Hampshire. These changes occurred because of the development and regional addition of call-switching equipment.
This photo and small article were part of an in-house publication at a time close to her retirement. She was working in Claremont, New Hampshire in 1969. As well as Nana and a very scary Santa, I am in the photo with my sister, a cousin, and a neighbour girl. You may click the image to load a very hefty PDF copy of it.
