Richard P. Gabriel

Subsequently, he pursued graduate studies in mathematics at MIT, from 1972 to 1973; he was tapped by Patrick Winston to become a permanent member of the artificial intelligence (AI) Lab at MIT, but funding difficulties made it impossible to retain him. Gabriel tried to start up, with Dave Waltz, an AI Lab at the University of Illinois at Urbana–Champaign, but after two years the lab fell through due to general apathy. During this time, from 1973 to 1975, Gabriel managed to earn an MS in mathematics.

Because of some of his mathematical work, Gabriel was then admitted to Stanford University; during that time (1975–1981), he served as a teaching assistant to John McCarthy, the founder of Lisp; he ported Maclisp from its native operating system, the Incompatible Timesharing System (ITS) to WAITS. He earned a PhD in computer science (on the topic of natural language generation); and he and his wife Kathy had a son. Around this time, he became a spokesperson for the League for Programming Freedom.

After earning a PhD, he continued to work on AI projects for McCarthy, although his thesis advisor was Terry Winograd. He eventually began working for Lawrence Livermore National Laboratory, where he recruited several of the researchers and programmers for a company, Lucid, Incorporated, he founded in 1984 and would leave in 1992. It survived until 1994.

Gabriel was at various times the President and Chairman of Lucid Inc. The product the company shipped was a Lisp integrated development environment (IDE) for Sun Microsystems’ reduced instruction set computer (RISC) hardware architecture named SPARC. This sidestepped the main failure of Lisp machines by, in essence, rewriting the Lisp machine IDE for use on a more cost-effective and less moribund architecture. During this time, Gabriel married his second wife, and had a daughter; he later divorced his second wife in 1993.

Eventually Lucid's focus shifted (during the AI Winter) to an IDE for C++. A core component of the IDE was Richard Stallman’s version of Emacs, GNU Emacs. GNU Emacs was not up to Lucid’s needs, however, and several Lucid programmers were assigned to help develop GNU Emacs. Friction arose between the programmers and Stallman over how to handle graphical user interface (GUI) issues, and Lucid forked Emacs, and thus became mainly responsible for the birth of what would come to be called XEmacs. One of his hires was another notable programmer, Jamie W. Zawinski.

After Gabriel left Lucid, Inc. for good, he became a Vice President of Development for ParcPlace Systems (1994–1995), and then a consultant, for, among others, Aspen Smallworks, before joining Sun Microsystems as a Distinguished Engineer.[2] There, Gabriel was an influential contributor to the evolution of the open source software strategy,[3] culminating in publication of the book Innovation Happens Elsewhere.[4] In 2007, he joined IBM Research as a Distinguished Engineer.

Gabriel has received the Association for Computing Machinery's (ACM) 1998 Fellows Award,[5] and its 2004 ACM-AAAI Allen Newell Award.[6] The citation reads: “For innovations in programming languages and software design, and promoting the interaction between computer science and other disciplines, notably architecture and poetry.”[6]

He was chairman of the Object-Oriented Programming, Systems, Languages & Applications (OOPSLA) conference in 2007.

In 1998 he received his MFA in Poetry from Warren Wilson College. He has published poems in some literary journals. His chapbook, Drive On, was published by Hollyridge Press in 2005.
