'''Interlisp''' (also seen with a variety of capitalizations) is a programming environment built around a version of the programming language [[Lisp (programming language)|Lisp]]. Interlisp development began in 1966 at Bolt, Beranek and Newman (renamed [[BBN Technologies]]) in [[Cambridge, Massachusetts]] with Lisp implemented for the [[Digital Equipment Corporation]] (DEC) [[PDP-1]] computer by [[Daniel G. Bobrow|Danny Bobrow]] and D. L. Murphy. In 1970, [[Alice K. Hartley]] implemented [[BBN LISP]], which ran on [[PDP-10]] machines running the [[operating system]] [[TENEX (operating system)|TENEX]] (renamed [[TOPS-20]]). In 1973,<ref>{{cite web |url=https://interlisp.org/docs/IRM.pdf |title=Interlisp Reference Manual |date=1993 }}</ref> when [[Daniel G. Bobrow|Danny Bobrow]], [[Warren Teitelman]] and [[Ronald Kaplan]] moved from BBN to the Xerox Palo Alto Research Center ([[PARC (company)|PARC]]), it was renamed Interlisp. Interlisp became a popular Lisp development tool for [[artificial intelligence]] (AI) researchers at [[Stanford University]] and elsewhere in the [[Community of practice|community]] of the Defense Advanced Research Projects Agency ([[DARPA]]). Interlisp was notable for integrating interactive development tools into an [[integrated development environment]] (IDE), such as a [[debugger]], an automatic correction tool for simple errors (via do what I mean ([[DWIM]]) software design),<ref>{{cite journal |last=Teitelman |first=Warren |date=April 1972 |title="Do What I Mean": the programmer's assistant |journal=Computers and Automation |pages=8–11 }}</ref> and analysis tools.
