Wenner discusses his professional experiences at Texas Instruments and his long career in consulting at McKinsey & Company. He explains how he became involved with the Kavli Institute for Theoretical Physics at UC Santa Barbara and how an interest in reading physics books grew into a full time pursuit curating what would become a singular library of rare physics manuscripts. Wenner describes how he built the collection and the various considerations that led to him deciding to work with AIP and to create the Wenner Collection. He describes the process that went into his book History of Physics, and he discusses his current interest collecting manuscripts relating to climate change.
