Citizens of the German Democratic Republic (GDR) who moved to the Federal Republic of Germany (FRG) in the 1980s later incorporated their migration experience into their biographies as success stories. When they relocated, they were between thirty and forty years old and had families. They migrated at a point in their lives when they had already acquired a lot of practical knowledge, if through experience in a different context. Their relocation was about much more than a change of residence, however. GDR citizens also had to come to terms with a new political system, bureaucracy, and society. What practical knowledge could they use to master their new situation? How did they experience their initial encounters with the new system, their search for employment, and their children’s education?
It is striking how profoundly we have come to integrate technological artifacts into our lives and how commonplace these devices appear to us now. There were times when they were entirely new. Just think of indoor water taps replacing public wells, or electric light bulbs supplanting kerosine lamps and gas fixtures. Here I consider how new technologies associated with engineered water supplies became a part of standard household practice in the late nineteenth and early twentieth centuries. Specifically, I explore the role that knowledge played in the process in Los Angeles. This city offers a thought-provoking glimpse into the “appropriation of technology” around 1900.
