Sander, Wendell B.

Biographical Notes

Wendell B. Sander received a Ph.D. in Electronics from Iowa State University. He joined Fairchild circa 1964 where he pioneered the design of gate arrays and semiconductor memory, including the first major computer design to use semiconductors in a main memory application (Illiac IV). In 1968 he was listed on the R & D Professional Staff - Org, Chart as head of the Complex Array Engineering section of the Digital Integrated Electronics Deptartment reporting to R. Seeds. He joined Apple Computer in 1977 as the 16th employee where he designed Apple II peripherals and the Apple III computer. In 1985 he founded a contract design engineering company, The Engineering Department, Inc. Projects included the technology used to found Echelon Corporation. In 1987 he co-founded Mpulse Microwave, a microwave and RF diode manufacturer, as the primary investor. In 1990 he joined General Magic, Inc. as Fellow providing new technology guidance in the development of PDAs. In 1992 he co-founded ChipScale, Inc. to exploit a new semiconductor packaging concept.
