"  WITHOUT  Dennis MacAlistair Ritchie  there is no c.If there is no C,there is no C++ that means no UNIX,WINDOWS,LINUX, No crysis and other cool games ,No photoshop ,No firefox,No VLC,No FL studio,NOPlaystation,NO XBOX  and  the list continues .90%of the applications in the world are written in Cand C++"   .

PERSONAL LIFE:
 Dennis MacAlistair Ritchie was born on September 9, 1941 and found dead October 12, 2011
Ritchie was born in Bronxville, New York. His father was Alistair E. Ritchie, a longtime Bell Labs scientist and co-author of The Design of Switching Circuits on switching circuit theory.
 He moved with his family to Summit, New Jersey, as a child, where he graduated from Summit High  School.Ritchie graduated from Harvard University with degrees in physics and applied mathematics.
 In 1967, he began working at the Bell Labs Computing Sciences Research Center, and in 1968, he received a  PhD from Harvard under the supervision of Patrick C.

INTRODUCTION OF C:
The introduction of Intel's 4004 microprocessor in 1971 is widely regarded as a key moment in modern computing, the contemporaneous birth of the C programming language is less well known. Yet the creation of C has as much claim, if not more, to be the true seminal moment of IT as we know it; it sits at the heart of programming — and in the hearts of programmers — as the quintessential expression of coding elegance, power, simplicity and portability.
 
  Fischer, his doctoral dissertation being "  Program  Structure and Computational Complexity".
  He is an American computer scientist who "   helped shape the digital era "   .
 He created the C programming language and, with long-time colleague Ken Thompson, the UNIX operating system.
SPIRTUAL DESCENDANTS:

        Ritchie and Thompson received the Turing Award from the ACM in 1983, the Hamming Medal from the  IEEE in 1990 and the National Medal of Technology from President Clinton in 1999. Ritchie was the head    of Lucent Technologies System Software Research Department when he retired in 2007. He was the 'R' in K&R C and commonly known by his username dmr.
"  1998 US National Medal of Technology"

C AND UNIX:

Ritchie was best known as the creator of the C programming language, a key developer of the UNIX operating system, and co-author of The C Programming Language, and was the 'R' in K&R (a common reference to the book's authors Kernighan and Ritchie). Ritchie worked together with Ken Thompson, the scientist credited with writing the original Unix; one of Ritchie's most important contributions to Unix was its porting to different machines and platforms.


      C AND UNIX

The C language is widely used today in application, operating system, and embedded system development, and its influence is seen in most modern programming languages. UNIX has also been influential, establishing concepts and principles that are now precepts of computing.

Ritchie was elected to the National Academy of Engineering in 1988 for
 "  Development of the 'C' programming language and for co-development of the UNIX operating system."
   Awards

TURNING AWARD:
Ken Thompson and Dennis Ritchie
In 1983, Ritchie and Thompson received the Turing Award for their development of generic operating systems theory and specifically for the implementation of the UNIX operating system. Ritchie's Turing Award lecture was titled "Reflections on Software Research".

IEEE EICHARD W.HAMMING MEDAL

In 1990, both Ritchie and Thompson received the IEEE Richard W. Hamming Medal from the Institute of Electrical and Electronics Engineers (IEEE), "for the origination of the UNIX operating system and the C programming language".





FELLOW OF THE COMPUTER HISTORY MUSEUM:

In 1997, both Ritchie and Thompson were made Fellows of the Computer History Museum, "for co-creation of the UNIX operating system, and for development of the C programming language."

NATIONAL MEDAL OF TECHNOLOGY:

On April 21, 1999, Thompson and Ritchie jointly received the National Medal of Technology of 1998 from President Bill Clinton for co-inventing the UNIX operating system and the C programming language which, according to the citation for the medal, "led to enormous advances in computer hardware, software, and networking systems and stimulated growth of an entire industry, thereby enhancing American leadership in the Information Age".

JAPAN PRIZE:

In 2011, Ritchie, along with Thompson, was awarded the Japan Prize for Information and Communications for his work in the development of the Unix operating system.








DEATH AND LEGACY:

Ritchie was found dead on October 12, 2011, at the age of 70 at his home in Berkeley Heights, New Jersey, where he lived alone.First news of his death came from his former colleague, Rob Pike.The cause and exact time of death have not been disclosed. He had been in frail health for several years following treatment for prostate cancer and heart disease. His death came a week after the death of Steve Jobs, although Ritchie's death did not receive as much     media coverage.Computer historian Paul E.
               
"  Ritchie was under the radar. His name  was not a household name at all, but... if you had a microscope and could look in a computer,   you'd see his work everywhere inside."  
                               ---Ceruzzi said after his death

The Fedora 16 Linux distribution, which was released about a month after he died, was dedicated to his memory.
