Raymond M. Holt (born in 1944) is an American computer designer and businessman in Silicon Valley.

He is best known for designing the first commercial microprocessor, the Intel 4004.

Seymour Roger Cray (September 28, 1925, October 5, 1996) was an American electrical engineer, computer scientist, mathematician, and supercomputer architect who designed a series of computers that were the fastest in the world for decades, and founded Cray Research, which built many of these machines.

Douglas Carl Engelbart (January 30, 1925, July 2, 2013) was an American engineer, inventor, and a pioneer in many aspects of computer science.

Edgar Frank "Ted" Codd (19 August 1923-18 April 2003) was a British computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases and relational database management systems.

Alan Emtage (born November 27, 1964) is a Bajan-Canadian computer scientist who conceived and implemented the first version of Archie, a pre-Web Internet search engine for locating material in public FTP archives.

Raymond Samuel Tomlinson (April 23, 1941, March 5, 2016) was an American computer programmer who invented the first email program on the ARPANET system, the precursor to the Internet, in 1971; it was the first system able to send mail between users on different hosts connected to ARPANET.

David Reeves Boggs (June 17, 1950, February 19, 2022) was an American electrical and radio engineer who developed early prototypes of Internet protocols, file servers, gateways, network interface cards and, along with Robert Metcalfe and others, co-invented Ethernet, the most popular family of technologies for local area computer networks.

Invented by Herman Hollerith

In the late 1920s and into the 1930s, Emanuel Goldberg developed what he called a "Statistical Machine" for searching microfilm archives using an optical code recognition system.

In late 1955, Johnson and his team presented the first-ever functioning hard drive to IBM management.

Ray Kurzweil invented the Kurzweil Reading Machine, the first device to transform print into computer-spoken words, enabling blind and visually impaired people to read printed materials.
