Dennis Ritchie MacAlistair
I decided to do the chronicle talking about Mr. Dennis Ritchie (born in 1941) who
was anAmerican computer scientist whose contributions were the beginning of the
technologicalrevolution we live today. He is known as the "Father of the C
Language", because heoriginally initiated the development of the C programming
language in 1969 and with hislong time colleagues, Ken Thompson and Brian
Kernighan, created the Unix operatingsystem.Ritchie never saw programming as a
problem but rather as a puzzle to be solved. By 1973Ritchie and Thompson had
rewritten the Unix operating system, using "C" instead ofmachine language,
and had done massive testing on it.It was so easy to use that programmer
around the world were switching to smallermachines to do their programming,
giving up the larger computers they thought theywould never want to leave.Bell
Labs became Lucent Technologies Inc. and began selling Unix to developers,
creating anew division for the company.
Ritchie has attributed his success in part to the fact that he was not computer literate
andtherefore had an open mind to possibilities that others might not have thought
existed.
His great contributions to computer science have laid the foundation for the
developmentof new technologies such as the GNU/Linux or Mac OS X operating
systems, and the birthof new programming languages such as C++ and Java. He
passed away on October 12,2011 at the age of 70.
He told Investor's Business Daily: "The interesting thing is not the programming itself.
Butwhat is important is what you can achieve with the end results." And if that's the
case,then Ritchie has had a major effect on most, if not all, computer users today.
