High Voltage Research Laboratory (Digital Archives)

The photograph from the Caltech Archives demonstrates the High Voltage Laboratory at Caltech. This laboratory came from a partnership between the Southern California Edison (SCE) company and Caltech (“Ready, Set, Spark”).  The equipment was designed to withstand up to a million volts, which was more than could be produced by any other American laboratory at the time.  In the photo, the insulators are interconnected with wires to test different voltage currents (“High Volts Lab”).  The formal attire suggests that these researchers are using their knowledge to test energy production within a controlled environment. On a deeper level, this photograph symbolizes the increasing importance of scientific knowledge behind the transformation of early Los Angeles. It demonstrates that rapid growth through energy production came with extensive experimentation.  In addition, the High Volts Laboratory became known as the house of lightning, where electrical demonstrations were often conducted by inventors like Royal Sorensen (“From High Volts to High Energy Physics”).  This ties into Caltech developing as not only an academic institution but also as a site where real scientific challenges are researched and problem-solved. It plays a key driving force behind what makes large amounts of energy distributable across long transmission lines.
