"POPLOG" is a trade mark of the University of Sussex.
This Introduction to Pop-11 uses material produced over many years by colleagues in the School of Cognitive and Computing Sciences at Sussex University, including Steve Hardy, Max Clowes and John Gibson in the 1970s, and since then by colleagues at Sussex, Integral Solutions Ltd, The University of Massachusetts at Amherst, and Hewlett Packard Laboratories, including especially:
Harry Barrow, Ros Barrett, Graham Brown, Julian Clinton, Jonathan Cunningham, Chris Dollin, Ben du Boulay, Rob Duncan, Roger Evans, John Gibson, James Goodlet, Tom Khabaza, Rudi Lutz, Steve Knight (now Steve Leach), Clark Morton, Chris Mellish, Jon Meyer. Simon Nichols, Robin Popplestone, Ben Rabau, Allan Ramsay, Ian Rogers, Ben Rubinstein, Mark Rubinstein, Colin Shearer, Mike Sharples, Chris Slymon, Robert Smith, Chris Thornton, John Williams, David Young.
The chief architect of Poplog and Pop-11 was John Gibson, at Sussex University, who designed and implemented the core mechanisms on which everything else depends including the compilers, store management, and interfaces to external languages and the operating system (Unix and VMS).
The language Pop-11 would not have existed, but for some excellent ideas of Robin Popplestone in the late 60s, which provided the basis for the family of "Pop" languages.
During the 1990s some of the development of Poplog was done by the main commercial distributors Integral Solutions Ltd (ISL), working in collaboration with Sussex University. ISL were taken over in December 1998 by SPSS after which they stopped distributing Poplog as a commercial product.
Instead, in July 1999, Version 15.53 of Poplog became available free of charge with full system sources at the Free Poplog site in Birmingham University, including all the poplog languages Pop-11, Prolog, Common Lisp, Standard ML, and most recently Scheme:

Distribution information referring to ISL in this primer is out of date. ISL no longer distribute Poplog or Pop-11 (though they still use it in their Clementine datam-mining system). For more information about the change see

The Alphapop subset of Pop-11 for the Mac was developed by
Cognitive Applications Ltd
but it has not been updated for a long time, and does not run on
current Macs, as far as I know).
