James Rumbaugh

Dr. James Rumbaugh is a computer scientist and object methodologist who is best known for his work in creating the Object Modeling Technique (OMT) and the Unified Modeling Language (UML).

Rumbaugh led the development of OMT while at General Electric Research and Development Center, where he worked for over 25 years.

He joined Rational Software in 1994, and worked there with Ivar Jacobson and Grady Booch ("the Three Amigos") to develop UML. Later they merged their software development methologies, OMT, OOSE and Booch into the Rational Unified Process (RUP). In 2003 he moved to IBM, after its acquisition of Rational Software. He retired in 2006.

Jim has a B.S. in physics from MIT, an M.S. in astronomy from Caltech, and a Ph.D. in computer science from MIT.

He has written a number of books about UML and RUP together with Ivar Jacobson and Grady Booch.
