Chronicle Dennis Ritchie

Anuncio
Dennis MacAlistair Ritchie (September 9,
1941 – October 12, 2011), Graduate of
Physics and Applied Mathematics at
Harvard, was an American computer
scientist.1​Dennis Ritchie said that he
wasn't smart enough to be a physicist or
mathematician (he was), but he liked
programming. That is why in 1967 he
abandoned his postgraduate degree in
Applied Mathematics at Harvard to enter
the legendary Bell Laboratories.
Shortly after entering Bell Labs in the
1960s, at a time when computers did not
yet have an interoperable operating
system (the architecture could not be
transferred between several computers,
nor the same programs passed), he was
assigned to work together with Ken
Thompson in the development of the
MULTICS Operating System, but this OS.
They found it too complicated, and very
heavy.
UNIX, a multipurpose and interoperable
operating system, meant a paradigm
shift and a technological revolution that
made software development more
efficient.
To keep up with the new UNIX system that had been written in assembly
code, between 1969 and 1973 Ken Thompson created the B language, but it
needed many improvements.
B was later replaced by the super-powered C, who was created by Ritchie. C
gave UNIX more flexibility and allowed it to be installed on multiple platforms.
C will not be the first programming language, but practically all of today's
languages descend from it: Java, C++, Microsoft's C#, Objective C, Swift,
Python, Ruby, PHP, etc.
He died at the age of 70 on the night of
Wednesday, October 12, 2011 in the
company of his family. His friend Robert
Pike was the first to break the news
through the Google+ social network.
