Successor Global Graphics

Harlequin was formerly a technology company based in Cambridge, UK and Cambridge, Massachusetts. They specialized in printing applications, graphical applications, law enforcement applications, and programming language implementations. Harlequin employees sometimes referred to themselves as "The 'Late Binding' company" and the company eventually evolved into a Think Tank for advanced technologies.

After Global Graphics purchased Harlequin, they spun off the Lisp, AI, and law enforcement application groups as Xanalys, and they spun off the Harlequin Dylan team as Functional Objects. Global Graphics acquired Harlequin primarily for the PostScript technologies, and it still continues to develop and market them under the Harlequin name.

Harlequin had two main lines of business

Other products included data analysis tools created using LispWorks, the Lisp IDE.

The Think Tank structure of the Harlequin can also be recognized via the development of a flexible and modular memory management system, the Memory Pool System (MPS). MPS was designed

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.

Harlequin Limited was founded in 1987 by Jo Marks in Cambridge, England, and the first offices were located in the founder's home in Cambridge. The company later moved to an office on Station Road, Cambridge, then in 1989 relocated to Barrington Hall, in the village of Barrington near Cambridge, which became the permanent company headquarters.

Expansion followed, and Harlequin Limited became The Harlequin Group Limited, with wholly owned subsidiaries in the UK (Harlequin Limited), the United States (Harlequin, Inc. - office opened in Cambridge, Massachusetts in 1993) and Australia (Harlequin Australia Pty Limited). The company acquired in February 1995 the rights to the Lisp-related technology Lucid Common Lisp of Lucid, Inc., that went out of business the summer before due to financial hardships. Many of the newly hired American Lisp staff had previously worked for Lucid Inc. and Symbolics, other Lisp companies which had previously failed. In 1997 the group company became Harlequin Group plc.
