I received the following announcement for an upcoming (San Francisco, California) Bay Area Computer History Perspectives Lecture. Raphael Robinson found M13 through M17 on the SWAC in 1952 Alex Hurowitz worked on the SWAC. Alex later found M19 and M20 on an IBM 7090.

View The first computer built in California was built in Los Angeles, of all places, not in Silicon Valley. It was the SWAC, the Standards Western Automatic Computer, and it was built for the National Bureau of Standards by Harry Huskey, our speaker this evening. Harry originally thought of building a computer in California after a succession of hard winters in Ohio and in England (where he worked for Alan Turing, on the Automatic Computing Engine, the ACE, a development from the Colossus, the early British computer used to break German codes in WWII). When Harry arrived at UCLA, where the Bureau of Standards had an Institute for Numerical Analysis, he found an empty room, and no electronic equipment of any kind. Harry hired three engineers (one for arithmetic, one for memory, and one for the control circuits) and set to work. Available components were mainly vacuum tubes---germanium diodes were delicate and hot and drifted, silicon junction diodes came later, and usable transistors were even further off into the future. When the SWAC was put into service in 1950, after two years of development, it was the fastest computer in the world at that time. The software was written by the people who built the machine, and included various routines for numerical analysis but no operating system, that was off into the future too. The SWAC was retired in 1957, after transistors and operating systems and programmers had all appeared on the scene. Harry Huskey went on after the SWAC to build the Bendix G-15 computer, often called the first personal computer, because although the size of a large refrigerator it was the first computer designed for dedicated use by a single individual. In 1960-62 Harry served as president of the ACM, which awards the Turing prize annually for the leading achievements in computer science, named after Alan Turing, Harry's former manager in the U.K. Most recently, Harry served as Prof. of Computer Science at UC Santa Cruz. ======================================================================== Admission free as always, no charge, no advance registration. Directions to Sun Building 6 Take San Antonio Road North exit from highway 101 in Mt. View, towards the Bay. Go one block past the traffic lights, and then: - turn right on Casey Ave. - turn right again after a block onto Marine Way. - go one block down Marine Way, and then turn left on Coast Ave. - go down to the end of Coast Ave., and Building 6 is on your right.
