Edsger Wybe Dijkstra
(11 May 1930 – 6 August 2002) was a Dutch computer scientist.

A theoretical physicist by training,
he worked as a programmer at the Mathematisch Centrum
(Amsterdam) from 1952 to 1962.

He was a professor of mathematics
at the Eindhoven University of Technology (1962–1984)
and a research fellow at the Burroughs Corporation (1973–1984).

He held the Schlumberger Centennial Chair
in Computer Sciences at the University of Texas at Austin
from 1984 until 1999,
and retired as Professor Emeritus in 1999.



One of the most influential members of
computing science's founding generation,
Dijkstra helped shape the new discipline
from both an engineering and a theoretical perspective.

His fundamental contributions cover diverse areas of
computing science,
including compiler construction, operating
systems, distributed systems, sequential
and concurrent programming, programming
paradigm and methodology, programming
language research, program design, program
development, program verification,
software engineering principles, graph
algorithms, and philosophical foundations
of computer science and computer programming.

Many of his papers are the source of new
research areas. Several concepts and
problems that are now standard in computer
science were first identified by Dijkstra
and/or bear names coined by him.



Computer programming in the 1950s to 1960s
was not recognized as an academic
discipline and unlike physics there were
no theoretical concepts or coding systems.
Dijkstra was one of the moving forces
behind the acceptance of computer
programming as a scientific discipline.

A training background in mathematics and
physics led to his applying similar
disciplines of mathematical logic and
methodology to computer programming.

In 1968, computer programming was in a state
of crisis. Dijkstra was one of a small
group of academics and industrial
programmers who advocated a new programming style
to improve the quality of programs.

Dijkstra coined the phrase
"structured programming" and during the
1970s this became the new programming
orthodoxy. Dijkstra's ideas about
structured programming helped lay the
foundations for the birth and development
of the professional discipline of software
engineering, enabling programmers to
organize and manage increasingly complex
software projects.

Dijkstra was an early theoretical pioneer
in many research areas of computing
science, including algorithm design,
programming methodology, and software
architecture. The academic study of
concurrent computing and concurrent
programming started in the 1960s, with
Dijkstra (1965) credited with being the
first paper in this field, identifying and
solving the mutual exclusion problem.

He was also one of the early pioneers of the
research on principles of distributed
computing. His foundational work on
concurrency, semaphores, mutual exclusion
(mutex), deadlock (deadly embrace),
finding shortest paths in graphs, fault-
tolerance, self-stabilization, among many
other contributions comprises many of the
pillars upon which the field of
distributed computing is built.

Shortly before his death in 2002, he
received the ACM PODC Influential-Paper
Award in distributed computing for his work
on self-stabilization of program computation.

This annual award was renamed
the Dijkstra Prize (Edsger W. Dijkstra Prize
in Distributed Computing) the following
year, in his honor.
