Richard Philip Mount, retired from his most recent position as head of Experimental Particle Physics Computing at SLAC National Laboratory, is interviewed by David Zierler. Mount recounts his childhood in Yorkshire, England and he describes the English education system and the opportunities that allowed him to pursue an undergraduate degree in physics at Oxford. He discusses his graduate experience at Cambridge, where he focused on bubble chamber physics, which drew him to research at CERN during the latter portion of his thesis work and for his postdoc, where he began to work with computers in a sustained way. Mount discusses is subsequent postdoctoral position at Oxford where he focused on muon beams, and his next research project working with Sam Ting at DESY to work on the MARK-J and L3 experiments. He describes the origins of the CMS collaboration and he explains that his original connection to SLAC came via the doomed SSC project, for which he served on the computing planning committee. Mount describes his initial work at SLAC providing computer expertise for the BaBar project, and how his expertise soon drew him into many other experiments at SLAC in his capacity as head of the Computing Department. He discusses his work as head of ATLAS Computing and his long term involvement in Geant4. At the end of the interview, Mount conveys his mixed feelings about retiring at a time when the value of computational analysis at SLAC had fully come into its own, but just at the time that SLAC was slowly moving away from particle physics toward astrophysics.
