&amp;#039;&amp;#039;&amp;#039;David H. D. Warren&amp;#039;&amp;#039;&amp;#039; is a [[computer scientist]] who worked primarily on [[logic programming]] and in particular the [[programming language]] [[Prolog]] in the 1970s and 1980s. Warren wrote the first [[compiler]] for Prolog, and the [[Warren Abstract Machine]] execution environment for Prolog is named after him.&lt;br /&gt;
&lt;br /&gt;
==Early life and education==&lt;br /&gt;
Warren received a [[Doctor of Philosophy|Ph.D.]]&amp;lt;ref&amp;gt;{{Cite thesis|degree=PhD|date=1978|title=Applied logic : its use and implementation as a programming tool|language=en|hdl=1842/6648|last1=Warren|first1=David H. D.}}&amp;lt;/ref&amp;gt; in [[artificial intelligence]] from the [[University of Edinburgh]] in 1977 under advisor [[Robert Kowalski]], and (a second advisor) [[Donald Michie]].&amp;lt;ref&amp;gt;{{MathGenealogy|id=127986}} -- (accessed 10 August 2014)&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Career==&lt;br /&gt;
Warren worked for the [[Artificial Intelligence Center]] at [[SRI International]] in the 1980s.&amp;lt;ref&amp;gt;{{cite web |title= David H.D. Warren |work= Alumnus of the Artificial Intelligence Center  |publisher= [[Artificial Intelligence Center]] |url= http://www.ai.sri.com/people/warren  |access-date=2010-05-26}}&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;{{cite news |author= Nils J. Nilsson |author-link= Nils J. Nilsson|title= Introduction to the COMTEX Microfiche Edition of the SRI Artificial Intelligence Center Technical Notes |url= http://www.aaai.org/ojs/index.php/aimagazine/article/download/424/360 |page= 49 |work= AI Magazine |volume= 5 |number= 1 |year= 1984 }}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
He founded the company Quintus Computer Systems in 1983 with William Kornfeld, Lawrence Byrd, Fernando Pereira and [[Cuthbert Hurd]] to commercialize the Prolog compiler, [[Quintus Prolog]].&amp;lt;ref&amp;gt;{{cite book |title=The Artificial intelligence report |url=https://books.google.com/books?id=xILpAAAAMAAJ |year=1983 |publisher=Artificial Intelligence Publications}}&amp;lt;/ref&amp;gt; Quintus was sold to [[Intergraph Corporation]] in 1989.&amp;lt;ref&amp;gt;{{cite book |title= The Engineering Design Revolution:The People, Companies and Computer Systems That Changed Forever the Practice of Engineering |author= David E. Weisberg |chapter= Intergraph |chapter-url= http://www.cadhistory.net/chapters/14_Intergraph.pdf |year= 2008 |access-date= 26 May 2010 |archive-date= 7 July 2010 |archive-url= https://web.archive.org/web/20100707074339/http://www.cadhistory.net/chapters/14_Intergraph.pdf |url-status= dead }}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
He has also held an academic position at the [[University of Bristol]] Department of Computer Science.&amp;lt;ref&amp;gt;{{cite book|chapter=Traffic patterns in a scalable multiprocessor through transputer emulation|publisher=[[IEEE]]|doi=10.1109/HICSS.1992.183173|title=Proceedings of the Twenty-Fifth Hawaii International Conference on System Sciences|pages=267–276 vol.1|year=1992|last1=Raina|first1=S.|last2=Warren|first2=D.H.D.|isbn=0-8186-2420-5|s2cid=62278813}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
