[edit] Career

After receiving a Ph.D. in 1972 from Stanford University in electrical engineering (specializing in man-machine systems), Ralph joined the Xerox Palo Alto Research Center (PARC). At PARC Ralph participated in development of the Xerox Star Workstation, the first commercial product to use mice, icons and windows.

Ralph then became vice president of applications at Metaphor Computer Systems, a decision support software and services provider. He developed the Capsule Facility in 1982. The Capsule was a graphical programming technique which connected icons together in a logical flow, allowing a very visual style of programming for non-programmers. The Capsule was used to build reporting and analysis applications at Metaphor.

Ralph founded Red Brick Systems in 1986, serving as CEO until 1992. Red Brick Systems, now owned by IBM, was known for its lightning fast relational database optimized for data warehousing.
