John Mashey, MIPS Team (MIPS first commercial RISC outside of IBM)
Seymour Cray is the Kelly Johnson of computing. Growing up not far apart (Wisconsin, Upper Michigan), one built the fastest computers, the other built the fastest airplanes, project after project.
Both fought bureaucracy, both led small teams, year after year, in creating awe-inspiration technology progress.
Both will be remembered for many years.
