Biographical Notes

Rex Rice was born in Douglas, Arizona, and graduated from Stanford University in 1940 with a degree in mechanical engineering. He joined Douglas Aircraft and later Northrup Aircraft and conducted research in stress analysis of sloped-wing design. In 1955, Rice joined the IBM Research Laboratory in Poughkeepsie, New York, where he took part in the development of the first fully transistorized digital calculator. His expertise in high-level language computing led him to join the Fairchild Semiconductor R&D Laboratory, Palo Alto circa 1963 to establish a department to investigate opportunities for ICs in digital system applications. He proposed many improved packaging designs and co-invented the dual-in-line package with Bryant “Buck” Rogers and Don Forbes. In 1966 he was listed on the R&D Professional Staff organizational chart as Manager of the Digital Systems Research Department reporting to Gordon Moore. Rice led the development of the SYMBOL computer and in 1970 the semiconductor memory system for the Illiac IV computer. Later, Rice held successive engineering management positions at the Fairchild Systems Technology Division, including Director of Technology, Manager – Multi-chip Memories, Director of Memory Systems Operations, and Director of Advanced Systems Development, He retired from Fairchild to become a consulting engineer in 1980.
