An electrical engineer and physicist, he was granted 28 patents for his designs of vacuum-tube-based business computers for IBM in the '50's. A graduate of Iowa State University, he was the central witness in the patent dispute as to whether ENIAC or the Atanasoff-Berry Computer was the first digital electronic device. (Like ABC's inventor Atanasoff, Richards was associated with Iowa State.) This book discusses diode switching circuits, circuit logic systems, magnetic core systems, non-magnetic storage, circuits and tubes for decimal counting, and analog-to-digital and digital-to-analog converters." 040414B.
