Intentional Software builds on the Intentional Programming project led by Charles Simonyi at Microsoft Research. The Death of Computer Languages, The Birth of Intentional Programming describes the vision for that project; there is also a video. The Intentional Programming system enabled programs to be written and viewed in a variety of specific notations, and also permitted the smooth integration of domain-specific and general-purpose programs.
Intentional Software Corporation was founded in August, 2002 by Dr. Charles Simonyi and Professor Gregor Kiczales, the leader of the research team for aspect-oriented programming and the AspectJ programming language at Xerox PARC. Gregor Kiczales has returned as a full time professor of computer science at the University of British Columbia.
