Father of the Supercomputer
Widely acknowledged as the "Father of the Supercomputer," Seymour Cray is credited with developing the first fully transistorized supercomputer in 1958. He was a founding employee of Control Data Corporation in 1957, and directed its engineering department until 1965. He developed an innovative cooling system for the CDC 6600 that allowed for higher performance. After leaving CDC in 1972 and founding Cray Research, he developed the CRAY-1 vector register technology.
Much of what Cray developed paved the way for subsequent developments in computer technology.
