Seymour Roger Cray (September 28, 1925[1] – October 5, 1996[2]) was a U.S. electrical engineer and supercomputer architect who designed a series of computers that were the fastest in the world for decades, and founded the company Cray Research which would build many of these machines. Called "the father of supercomputing,"[2] Cray has been credited with creating the supercomputer industry.[3] Joel Birnbaum, then CTO of HP, said of him:


Early life

Cray was born in 1925 in Chippewa Falls, Wisconsin to Seymour R. and Lillian Cray. His father was a civil engineer who fostered Cray's interest in science and engineering. As early as the age of ten he was able to build a device out of Erector Set components that converted punched paper tape into Morse code signals. The basement of the family home was given over to the young Cray as a "lab".

Cray graduated from Chippewa Falls High School in 1943 before being drafted for World War II as a radio operator. He saw action in Europe, and then moved to the Pacific theatre where he worked on breaking Japanese codes. On his return to the United States he received a B.Sc. in Electrical Engineering at the University of Minnesota, graduating in 1949. He also was awarded a M.Sc. in applied mathematics in 1951.
