Dennis Ritchie (9th September, 1941 – 12th October, 2011):
Dennis MacAlistair Ritchie, formally known as Dennis Ritchie was an American computer scientist who created C Programming Language with Ken Thompson. He was the Head of Lucent Technologies System Software Research Department. He was commonly very well known as username ‘DMR (Short form of Dennis MacAlistair Ritchie)’.
He was born in Bronxville, New York, United States of America (USA) on 09thSeptember, 1941. His father Alistair E. Ritchie was also scientist at Bell Labs. Ritchie studied from Summit High School and graduated from Harvard University with degrees in applied mathematics and physics.
In 1967, He started working with Bell Labs Computing Sciences Research Center.
In 1968, He received Ph.D from Harvard University under the dissertation entitled ‘Program Structure and Computational Complexity’.
C language is one the most useful programming language widely used in operating system, application, embeded systems development. Also, it plays an important role in building modern programming environment.
In 1983, Dennis Ritchie and Ken Thompson got Turing Award for the development of Generic Operating Systems Theory for the implementation in UNIX operating system.
In 21st April 1999, Dennis Ritchie and Ken Thompson received National Medal of Technology from 42nd President of the United States, Bill Clinton for co-inventing the C Programming Language and UNIX operating system.
In 2005, Industrial Research Institute awarded Dennis Ritchie with its Achievement Award.
In 2011, again Ritchi and Thompson was awarded Japan Prize for Information and Communications.
