Deep LA Conference at The Huntington
I’ll be presenting a paper at the “Deep L.A.” graduate history conference taking place at The Huntington on October 3rd.
The conference is sponsored by UCLA and USC, with a focus on Los Angeles and Southern California regional history: http://lahistoryconference.tumblr.com
I’m presenting a portion of a chapter in my dissertation, which focuses on mainframes, paperwork, and the electrical utility company Southern California Edison during the postwar era.

People Working in Computer Room
As part of my dissertation I’m working with the Southern California Edison Photographs and Negatives collection at the Huntington Library. The photographic collection is now available online at the Huntington Digital Library. A few years ago, when I first came across this collection, it was only available in-person on a single computer.
I stitched the two photos below into an animated gif, showing the transition within computerized space. The images are from “People working in computer room with 1” tape drives" in the SCE collection at the Huntington. These before and after photos taken in 1966 at SCE appear to show how people would fit alongside and interact with the mainframe computer.
Photographs such as these often show many people in the room, mostly trying to look busy, with a few of them staring at equipment or pretending to use the machine. These staged photographs for internal use are similar to those used for marketing. In both cases the images are designed to show how people and computers would work together.
The mainframe in these photographs is a Control Data Corporation mainframe, and it appears to be a CDC 3200 system.
The Computer History Museum in Silicon Valley has a brochure for the CDC 3200 mainframe (PDF) available online as well.
