Ronald Jay "Ron" Brachman (born 1949) is the director of the Jacobs Technion-Cornell Institute at Cornell Tech.
While at IPTO, he helped develop DARPA's Cognitive Systems research efforts.
When AT&T split with Lucent in 1996, he became Communications Services Research Vice President and was one of the founders of AT&T Labs.
He is considered by some to be the godfather[citation needed] of description logic, the logic-based knowledge representation formalism underlying the Web Ontology Language OWL.
[3] He is the co-author with Hector Levesque of a popular book on knowledge representation and reasoning[4][5] and many scientific papers.
