Fred Hauser, my maternal grandfather, emigrated to Los An- geles from Bern, Switzerland, in 1926. He was trained as a machinist, and perhaps inevitably for Swiss mechanical types, there was a bit of the watchmaker in him, too. Fortunately, at that time the young Hol- lywood was something of a clockwork industry, too, with its mechan- ical cameras, projection systems, and the new technology of magnetic audio strips. Hauser got a job at MGM Studios working on recording technology, got married, had a daughter (my mom), and settled in a Mediterranean bungalow on a side street in Westwood where every house had a lush front lawn and a garage in the back. But Hauser was more than a company engineer. By night, he was also an inventor. He dreamed of machines, drew sketches and then mechanical drawings of them, and built prototypes. He converted his garage to a workshop, and gradually equipped it with the tools of creation: a drill press, a band saw, a jig saw, grinders, and, most important, a full-size metal lathe, which is a miraculous device that can, in the hands of an expert operator, turn blocks of steel or alu- minum into precision-machined mechanical sculpture ranging from camshafts to valves.
