David H. D. Warren is a computer scientist (Ph.D. artificial intelligence, University of Edinburgh 1977). In the 1970s and 1980s he worked primarily on logic programming and in particular the programming language Prolog. Warren wrote the first compiler for Prolog. The Warren Abstract Machine execution environment for Prolog is named after him.
Warren worked for the Artificial Intelligence Center at SRI International in the 1980s.[1][2] He founded the company Quintus Computer Systems in 1983 with William Kornfeld, Lawrence Byrd, Fernando Perreira and Cuthbert Hurd to commercialize the Prolog compiler.[3] Quintus was sold to Intergraph Corporation in 1989.[4]
