REVOLUTION BY
Presented by Jimit Patel
DENNIS RITCHIE

2. Introduction
Dennis M.Ritchie – The father of
the “C” programming language
He was born on September 9,
1941, in Bronxville, New York.
Dennis was a scientist and
physicist who graduated from
Harvard University and was a
professor of applied
mathematics.

3. Ritchie started working at the Computer
Science Research center at Bell's labs in
1967, where his father had previously
worked.
Due to her dedication of about 15 hours of
work per day, both at home and in the labs,
he was head of the Systems Software
Research Department at Lucent
Technologies (an American
telecommunications company).
In 1990 she became head of the technical
research department at Bell Laboratories.
WORK & LIFE

4. He was in the labs there he met Ken
Thompson and it was in 1983 that they
both created the Multics project that
initially did not arouse the interest of Bell
executives, but with which they later won
the ACM Turing Award.
This award was received for his
development of the theory of generic
operating systems and for his
implementation of the UNIX operating
system, which was launched in 1973.
However, they did not have copyright on it.
THEIR PARTICIPATION

5. A year before the release of UNIX, Ritchie had
already developed a programming language that
later joined the B language, developed by
Thompson, giving rise to the C language.
With these developments, Ritchie has gained an
important place in the history of the computer
industry.
The C language continues to be used in the
development of applications and operating
systems and its influence can be seen in more
recent programming languages, such as C ++,
Java, C #, PHP and JavaScript.

6. Both of these men died in the same month of the same year. Steve was largely considered
a hero, while Dennis was largely ignored by the world. Only a handful of programmers who
know the real value of Dennis work even know of his death.
Without Steve Jobs there is no iPhone, iPad, iPod, or Macintosh. Without Dennis there is no
C language. Without C, there is no Unix, Windows, or Linux. Without C there is no C++ nor
Objective C. There is no MacOS X, no IOS, no Photoshop, no Firefox, no Safari, no Google
Chrome, no Playstation, no XBox. In fact, 90% of the applications in the world are written in
C or C++ or Objective C.
