People Who played a big role in computer industry


Eric Allman
Eric Allman is the main author of the send mail program, which is used by most Unix -like systems to deliver SMTP (emails), although certain alternatives have become popular, such as Daniel Bernstein's qmail program. Eric Allman is Kirk McKusick's partner.

Charles Babbage
Babbage is considered one of the forefathers of computer science for having designed and built the difference engine , and having imagined (with the help of Ada Lovelace) the analytical engine , which, although it was never built in his lifetime, can be considered as a true (mechanical) computer

John W. Backus
John Backus headed the development group at IBM which gave birth to the language FORTRAN (the oldest programming language, excepting theoretical concepts like the Lambda Calculus, and, of course, assembler). John Backus is the 1977 recipient of the ACM 's A. M. Turing Award  and a charter recipient of the IEEE Computer Society 's Pioneer Award .

Tim Berners-Lee
Tim Berners-Lee is the inventor of what is now known as the World Wide Web : his original proposal  for Information Management, circulated in 1989, is the founding idea of the hypertext information web; and he is the author of the original internet draft specifications of HTTP , HTML  and URL s in 1993 (current specifications: HTTP , XHTML  andURI ).

Vinton Cerf
Vinton Cerf is the father of the Internet. He and Bob Kahn are the principal architects of the Transmission Control Protocol (TCP) that is one of the foundational stones of the Internet as well as the earlier Network Control Protocol (NCP). His speech The Internet is for everyone, given at the Computers, Freedom and Privacy conference on April 7, 1999, defined the Internet Society’s new motto. Now Vinton Cerf's interests include planning the development of the Interplanetary Internet . Vinton Cerf is the 2004 recipient of the ACM 's A. M. Turing Award .

Sivasubramanian Chandrasegarampilai
Designer of the heuristically programmed ALgorithmic (HAL) computer.

Seymour R. Cray
in Colorado Springs, Colorado (USA). He founded Cray Research in 1972; in 1976, he unveiled the CRAY-1, the world's first supercomputer. Seymour Cray is a charter recipient of the IEEE Computer Society 's Pioneer Award .

Whitfield Diffie
Inventor of public key cryptography.

Edsger Wybe Dijkstra
Edsger Dijkstra is the inventor of the concept of semaphore, which is at the basis of all synchronized programming. He is also one of the main contributors to the language ALGOL. Edsger Dijkstra is the 1972 recipient of the ACM 's A. M. Turing Award  and a charter recipient of the IEEEComputer Society 's Pioneer Award . His famous speech, Go To Statement Considered Harmful , has become a classic.

Jim Ellis
Jim Ellis was co-creator of Usenet.

James Gosling
Gosling is the inventor of the Java  programming language.

Richard Greenblatt
Richard Greenblatt is the inventor of the Lisp machine, and his “betrayal” by the Symbolics team brought the end of the True Hackers' era.

David Albert Huffman
Inventor of a method for constructing binary trees which is of great importance in compression theory.

Robert E. Kahn
Bob Kahn and Vint Cerf are the principal architects of the Transmission Control Protocol (TCP) that is one of the foundational stones of the Internet. Bob Kahn is a 1996 recipient of the IEEEComputer Society 's Pioneer Award  and the 2004 recipient of the ACM 's A. M. Turing Award .

Brian Wilson Kernighan
Brian Kernighan is the co-inventor, with Alfred Aho and Peter Weinberg, of the Awk programming language. He is co-author, with Dennis Ritchie, of the Book on C . His critique  of the Pascal language is justly famous.

Augusta Ada King, Countess of Lovelace
She was a daughter of the poet Lord Byron. She is often counted as the first “programmer”, for her work on Babbage's Analytical Engine. The programming language Ada  is named after her.

John McCarthy
John McCarthy is the co-founder, with Marvin Minsky, of the Artificial Intelligence Laboratory  at MIT , where, among other things, the True Hackers were bred — and he was something of an uncle to them all. He is also the inventor of the name, if not the term, of “artificial intelligence”. He is the inventor of the Lisp programming language (the second oldest after FORTRAN, and still considered unequaled by some), in 1958.

Marvin Minsky
Marvin Minsky is the co-founder, with John McCarthy, of the Artificial Intelligence Laboratory  at MIT , where, among other things, the True Hackers were bred. Marvin Minsky has written many an influential text on artificial intelligence. Marvin Minsky is the 1969 recipient of the ACM 's A. M. Turing Award  and a 1995 recipient of theIEEE Computer Society 's Pioneer Award .

Blaise Pascal
Pascal is the inventor of a digital calculator (and consequently counted as one of the forefathers of computer science), the “Pascaline”, but it would seem, in fact, that a calculator had already been invented by Schickard in 1624. The programming language Pascal (invented by Niklaus Wirth) is named after Blaise Pascal (see also Brian Kernighan's critique of this language

Dennis M. Ritchie
Dennis Ritchie invented the C programming language, for use with Ken Thompson's recently invented Unix  system, during his work at AT&T Bell Labs  in 1969. He is co-author, withBrian Kernighan, of the Book on C . Dennis Ritchie is the 1983 recipient of the ACM 's A. M. Turing Award  (with Ken Thompson) and a 1994 recipient of the IEEE Computer Society 's Pioneer Award .

Claude Elwood Shannon
The father of information theory.

Bjarne Stroustrup
Stroustrup invended the C++  programming language.

Kenneth Thompson
Ken Thompson invented the operating system Unix during his work at AT&T Bell Labs  in 1970. Ken Thompson is the 1983 recipient of the ACM 's A. M. Turing Award  (with Dennis Ritchie) and a 1994 recipient of the IEEE Computer Society 's Pioneer Award .

Linus Benedict Torvalds
Linus is the author of the Linux  operating system kernel, which has, in a way, provided a successful term to the GNU project started by Richard Stallman.

Alan Mathison Turing
Turing was one ofAlonzo Church's doctoral students. In 1936, he defined what is now referred to as a “Turing machine”, and proved the universality theorem. He is often considered as the founder of computer science. During WW2, he became a hero by building a machine which could decode the German communications enciphered by means of the “enigma” device. He was homosexual and completely open about it; but homosexual acts were forbidden in England until 1966. After Turing was convicted in 1952, he was made to take hormonal injections which made him deeply unhappy. He died of cyanide poisoning, and while it is often thought to have been suicide, it was more probably accidental.

John von Neumann
Von Neumann is credited with the idea of having a computer store its instructions (code) in the same memory as it stores its data (rather than, e.g. in hardwired form). This makes him the inventor of the modern computer.

Larry Wall
He is the inventor of the Perl  programming language.

Niklaus E. Wirth
 Wirth is the inventor of the Pascal programming language (named in honor of Blaise Pascal). Niklaus Wirth is the 1984 recipient of the ACM 's A. M. Turing Award  and a 1987 recipient of the IEEE Computer Society 's Pioneer Award .

Stephen Wozniak
Wozniak designed the first “Apple” computer

The QWERTY Inventor
The American inventor Christopher Sholes designed the QWERTY keyboard. 

Ray Tomlinson
The history of email began with Ray Tomlinson in 1971. The program was created while he was working for the US government, specifically ARPANET (the future Internet).
Jorn Barger
Blog is short for weblog. The term weblog was first coined in December 1997 by an American blogger named Jorn Barger
