Eckert-Mauchly Computer Corporation (1946-1950)Founders: John Mauchly (PhD) and J. Presper Eckert (BEng), both met at the Moore School of Electrical Engineering, University of Pennsylvania and built the first electronic computer ENIAC for military.
Eckert-Mauchly Computer Corporation (1946-1950)In March 1946, Electronic Control Company is founded.The Electronic Control Company soon became the EckertMauchly Computer Corporation.An order from the National Bureau of Standards to build the Universal Automatic Computer (UNIVAC).In 1950, EMCC ran into financial troubles and was acquired by Remington Rand Corporation.Eckert continued working in Remington Rand (later merged with the Burroughs Corporation to become Unisys in 1986) until retired.The UNIVAC I was finished on December 21, 1950.

DEC Network technologies1970 1983, active in set up computer network protocols (with IBM, Honeywell, and universities).PDP/VAX family (with UNIX OS) has been used in many universities for network research.In 1984, DEC launched its first 10 Mbit/s Ethernet. DEC had produced a networked storage architecture which allowed them to compete directly with IBM. DEC also introduced the VAXcluster concept.

SUN Microsystems (1982 2010)On February 24, 1982, Vinod Khosla, Andy Bechtolsheim, and Scott McNealy, all Stanford graduate students, founded Sun Microsystems.
Bill Joy of Berkeley, a primary developer of the Berkeley Software Distribution (BSD), joined soon after and is counted as one of the original founders.
