Best Computer Scientist in the World - List and Ranking

List of Best Computer Scientists in the World - User's Vote and Ranking

A computer or a computer scientist is a person who pursues a profession in the study, design, production, management and maintenance of information processing systems. Informatico is the generic term to indicate one of the many professional figures employed in computer science in the business, industrial and scientific fields. These professions belong to the advanced tertiary sector. Since the beginning of the xxi century the term is differentiated with the operator who uses the computer as a tool for his own business. The profession of computer scientist brings together all the trades that consist of designing, coordinating or implementing the development or deployment of a computerized solution that will be made available to the operators then called users.

6. Dennis Ritchie

Dennis Ritchie

Born in Bronxville, New York, Ritchie graduated in physics and applied mathematics by Harvard University. In 1967 he began working at the Center for Research in Computational Sciences at Bell Labs. In 1983, he and Ken Thompson received the Turing Award for their development of generic operating system theory and especially for their implementation of the UNIX operating system.

7. Barbara Liskov

Barbara Liskov

She led the development of programming languages such as CLU and Argus in the 1970s and 1980s, as well as the object-oriented database management system Thor. Together with Jennet, Wing developed in 1987 the principle of substitution - the concept of defining a subtype.

9. Vinton Cerf

Vinton Cerf

Vinton Gray Cerf is an American computer scientist, considered one of the 'fathers' of the Internet. He graduated in mathematics and computer science at Stanford University (1965). During his subsequent stay at the University of California (UCLA) he obtained a master's degree in science and a doctorate.

10. Brian Kernighan

Brian Kernighan

He is famous above all for having collaborated with Dennis Ritchie, creator of the programming language C, to write the book C Programming Language, known, in the environment, as the K&R from the initials of its authors, reputed a fundamental text for the programmers. He is the creator of AWK languages, together with Alfred Aho and Peter Weinberger, and AMPL, as well as many Unix programs, such as troff.

23. John Backus

John Backus

John Backus was an American computer scientist. Winner of the Turing Prize in 1977 for his work in high-level programming systems, especially for his work with FORTRAN. To avoid the difficulties of programming the calculators of his time, in 1954 Backus was in charge of the direction of a research project in IBM for the project and realization of a programming language closer to the normal mathematical notation. From that project emerged the FORTRAN language, the first of the high-level programming languages that had a great, even commercial, impact on the emerging computer community. After the completion of FORTRAN, Backus was a very active member of the international committee that was in charge of the ALGOL language project.

24. John McCarthy

John McCarthy

Known for studies in the field of artificial intelligence and for being the creator of the Lisp programming language. He received the Turing Award in 1972 and the National Science Medal of the United States in 1991.
