Harlequin (software company)
software company
Harlequin was a technology company based in Cambridge, UK and Cambridge, Massachusetts. It specialized in application software for printing, graphics, law enforcement, artificial intelligence, and in implementations of programming languages. Harlequin employees sometimes referred to themselves as "The 'Late Binding' company" and the firm eventually evolved into a think tank for advanced technologies.
After Global Graphics purchased Harlequin, they spun off the application groups for Lisp, artificial intelligence (AI), and law enforcement as Xanalys, and they spun off the Harlequin Dylan team as Functional Objects. Global Graphics acquired Harlequin mainly for the PostScript technologies, and it still continues to develop and market them under the Harlequin name.
Think tank products
Harlequin had two main lines of business:
Digital prepress (mainly ScriptWorks, a PostScript language compatible raster image processor (RIP), now selling under the name Harlequin RIP)
Modern language development environments: compilers and integrated development environments (IDEs) for Lisp (LispWorks), ML (MLWorks), and Dylan (DylanWorks)
Other products included data analysis tools created using LispWorks, the Lisp IDE.
The think tank structure of Harlequin can also be recognized via the development of a flexible and modular memory management system, the Memory Pool System (MPS). MPS was designed to support:
A wide range of requirements from high-speed manual memory management, to complex garbage collection with many different types of reference
Two products: ScriptWorks PostScript RIP, and the Harlequin Dylan compiler and IDE for the Dylan language
Think tank spin-offs
In January 2005 employees founded the independently owned LispWorks Limited to focus on the Lisp business.
Several of Harlequin's other assets and technologies have also been acquired and open sourced by companies founded by former Harlequin employees.
Functional Objects Inc., was founded in 1999 to continue developing and producing the Dylan IDE. In 2004, all code was open sourced to The Gwydion Maintainers. They renamed the IDE to Open Dylan.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Harlequin (software company)”, the useful work is to connect “software company” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Oct 30, 2025. The linked authority identifier is Q5658641. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2005, 1999 and 2004.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
