Biographical Notes

Donald (Don) W. A. Forbes was a draughtsman and mechanical engineer who moved with Rex Rice and others from IBM Research Labs in Poughkeepsie, New York, to form the Fairchild Digital Systems Research Department circa 1963. In 1964 - 1965 he created the engineering drawings and contributed to the design of the ceramic dual-inline-package (DIP). See also entries on Rex Rice and Bryant Rogers. The DIP has been described as the most enduring IC package. The first devices were 14-lead ceramic devices with two rows of pins on 100 mil centers providing greater design freedom and an early de facto industry standard for package pin outs and footprints. A 1966 organization chart shows Forbes as head of the Packaging Development Section reporting to W. Steffe, Manager of the Device Development Department.
