'''Douglas B. Lenat''' is the CEO of [[Cycorp]], Inc. of Austin, Texas, the company he founded in 1994 to carry on the development and commercialization of the Cyc technology he initiated. He has been a prominent researcher in artificial intelligence, especially machine learning, knowledge representation, blackboard systems, and ontological engineering. He has also worked in military simulations and published a critique of conventional random-mutation Darwinism based on his experience with Eurisko.
 
At the University of Pennsylvania, Lenat received his Bachelor's degree in Mathematics and Physics, and his Master's degree in applied mathematics in 1972. He received his Ph.D. in Computer Science at Stanford in 1976. His Ph.D. thesis was a heuristic program called AM that made hundreds of small creative discoveries in mathematics -- a theorem proposer, rather than a theorem prover -- for which he was awarded the biannual IJCAI Computers & Thought Award in 1977.
 
Dr. Lenat was named one of the original Fellows of the AAAI (American Association for Artificial Intelligence). He is a prolific author, and has been a professor at CMU and Stanford, a founder of Teknowledge, and have served on the technical advisory boards of both Apple and Microsoft. His interest and experience in national security has led him to regularly consult for U.S. government agencies and the White House. From 1984 through 1994, Dr. Lenat directed the Cyc common sense knowledge base and reasoning project for MCC, the USA's first high-technology research consortium.

Douglas Bruce Lenat

Our friend and Ontology Summit collaborator Doug Lenat died on August 31, 2023. It was very sad news to all of us who worked with him, and a great loss to the community.
 
Doug was an American computer scientist and researcher in AI who was the founder and CEO of Cycorp, Inc. in Austin, Texas. He was awarded the biannual IJCAI Computers and Thought Award in 1976 for creating the symbolic machine learning program AM. The AM program made hundreds of small creative discoveries in mathematics -- a theorem proposer, rather than a theorem prover. He contributed to knowledge representation, cognitive economy, blackboard systems, and ontology engineering, a term he coined in 1984.
 
Doug was a professor at CMU and Stanford, and left academia to found the Cyc project in 1984. He was named one of the original Fellows of AAAI. He was a strong proponent of encoding commonsense knowledge (open knowledge networks are an attempt to do this). He played a major role in the development of the discipline of ontology engineering, especially through the Cyc project and Cycorp.
 
Doug was a contributor to the Ontolog community since 2005. He was actively involved in the very first Ontology Summit, dedicated to making upper ontologies interoperable. His Ontology Summit invited presentations include:
• "CYC: Lessons Learned in Large-Scale Ontological Engineering" ConferenceCall_2005_11_17
• Upper Ontology Summit presentation on OpenCyc UpperOntologySummitMeeting_2006_03_15
• "Is OpenCyc doomed to be the new Esperanto, or is OOR doomed to be the new Electronic Data Interchange, or -- even worse -- both!" ConferenceCall_2008_04_03
• "Representation and Reasoning Lessons Learned in Building Cyc" ConferenceCall_2022_02_02
 
He will be missed.
