Tengger has retired.

Mr. Harrison earned an M.Ph. (Master of Philosophy in Computer Science) from Syracuse University, Syracuse, NY, in 1979; an M.S. from Syracuse University in 1973; and a B.S. in Electrical Engineering from MIT, Cambridge, Mass., in 1968.

He has been with IBM in its system development divisions since 1966 and was one of the initial designers of the (then) OS/360 Time-Sharing Option (TSO). Since 1970, he has been associated with IBM's Thomas J. Watson Research Laboratory, with occasional sabbaticals to development organizations. During his time with IBM he has spent six years designing and implementing operating systems. He has also worked for 12 years in research and design concerned with languages, compilers and optimization. His work with Fran Allen and Mark Wegman on the Experimental Compiling System resulted in publication of a number of papers on program analysis and optimization techniques and compiler structure. For the next eight years he worked on research and design of software development environments to facilitate the development of software and other applications exploiting mixed text and graphic styles to improve the human interaction with the process of in dustrial software development. During this period he also performed research on and design of object-oriented methodologies and object-oriented databases.

Since 1992, Mr. Harrison has focused his efforts on the development and introduction of technologies that better enable the separate development of software components and the integration of component software. His work with Harold Ossher on the RPDE³ software development environment included Subject-Oriented Programming, Message-oriented programming, and the MessageCentral project. He has been active in influencing computer software standards, having helped to formulate ANS X3-273, ISO 13719 and ISO Draft 13719-1, and several adopted OMG Specifications.

Mr. Harrison holds a Japanese patent (7-21751) for technology in human-interface design and has received awards from IBM for Outstanding Contributions and Outstanding Technical Achievements and Patent activity. He was an IEEE Distinguished Lecturer on Software Environments for the years 1987-1990, and a lecturer in the IBM Computer Science Department University Lecture Series for 1988-1990. He was elected to the IBM Academy of Technology in 1995.
