Jack Bonnell Dennis (born October 13, 1931)[1] is an American computer scientist and Emeritus Professor of Computer Science and Engineering at Massachusetts Institute of Technology.

The work of Dennis in

hacker culture. As a Massachusetts Institute of Technology faculty member he sponsored easier access to computer facilities at MIT during the early development of the subculture.[2][3] Much of what would later become Unix came from his early collaboration with Dennis Ritchie and Ken Thompson
. This collaborative and open philosophy lives on today.

Dennis was also a member of the historic Tech Model Railroad Club, which incubated much of the early slang and traditions of hacking.

Early life and education

Dennis graduated from the Massachusetts Institute of Technology (MIT) as Bachelor of Science (1953), Master of Science (1954), and Doctor of Science (1958).[4] His doctoral thesis analyzed the relation between mathematical programming problems and electrical networks.[5] After completing his doctorate, Dennis became part of the MIT's Department of Electrical Engineering and Computer Science's faculty, being promoted to full professor in 1969.

Career

As a professor at MIT, Dennis was influential in the work of student

ARPA
.

Dennis was one of the founders of the

Ken Thompson (who also worked on the project) to design the first incarnation of Unix
. In recognition of his work on the Multics project, Dennis was elected as IEEE Fellow.

Dennis' research at the MIT focused in Computer Theory and Computer Systems, specifically:

  • Theoretical Models for Computation
  • Computation Structures
  • Structure of Computer Systems
  • Semantic Theory for Computer Systems
  • Semantics of Parallel Computation
  • Computer System Architecture

Dennis has also worked as an independent consultant and research scientist on projects related with parallel computer hardware and software since his retirement from MIT in 1987. He has worked with the NASA Research Institute for Advanced Computer Science as visiting scientist, with the Architecture Group of Carlstedt Elektronik (Gothenburg, Sweden), and with Acorn Networks, Inc., as Chief Scientist.[5]

A great part of Dennis' career has been devoted to non-

single assignment and dataflow, in which instructions are executed as soon as data are available (this specific model is called "static" in contrast to Arvind's "dynamic").[6]

In 2009, Dennis was elected a member of the National Academy of Engineering for contributions to sharing and protection in computer systems and parallel architectures based on data flow principles.
