Seymour Cray was a radio operator during his time at the end of the WWII -
-
Seymour Cray was apart of the "Battle of the Bulge" which cemented American confidence in WWII -
Seymour Cray earned a Bachelors in Electrical Engineering at the University of Minnesota. -
Seymour Cray earns his Mater Degree in Applied Mathematics from the University of Minnesota.
-
Seymour Cray was recommended by his professors at the University of Minnesota to work for the Engineering Research Associates (ERA) to build transformers. -
Seymour Cray develops the UNIVAC 1103 which was the first electronically digital computer to be accessed by the public. -
-
Seymour Cray replaces Vacuum tubes and radio valves with transistors which became the industry standard thereafter. In the picture you will see the evolution from vacuum tubes to the transistors and beyond. -
Seymour Cray creates the CDC 1604 which was the first commercial use of transistors with their computers -
Seymour Cray creates CDC 6600 which had three MFLOPS and 350,000 Transistors and was the first to use freon for cooling. The CDC 6600 was also considered to be the very first Super computer ever. -
Seymour Cray creates the CDC 6400 which was slower and less expensive than the CDC 6600 before it. -
Seymour Cray Creates the CDC 7600 that had ten to thirty six MFLOPS. Seymour Cray also create put created the CDC 7600 with a sense of style rather than the traditional lab look. With the creation of CDC 7600, Control Data Corporation surpasses the tech giant IBM. -
Seymour Cray Leaves CDC to create Cray Research Inc. -
Seymour Cray creates the Cray- 1 which replaced the transistors with the IC chip. The Cray -1 delivered 170 megaflops or processing spreed. -
The Cray -2 was created to push the envelop of processing speeds from the Cray-1 with 10000 MFLOPS ( which was ten times faster than the Cray -1). -
Seymour Cray Creates the Cray-3 but stop working on the Cray -3 in favor of a new design. The Cray - 3 was only used as a demonstration unit. The Cray- 3 was the last completed design from Seymour Cray. -
Seymour Cray formed Cray Computer Corporation in which he began to work on the Cray -4 -
Seymour Cray started to work on the Cray -4. Unfortunately the Cray Corporation Computers went bankrupt and the Cray - 4 was never finished.
