Nick Ing-Simmons was the auther of [Perl/Tk]. He [http://www.nntp.perl.org/group/perl.perl5.porters/2006/09/msg116654.html%|%died of a heart attack] at the age of 48 on 2006-09-26. [RLH] 2006-09-26: That is sad. Nick was always very helpful. ** Reference ** [http://news.perlfoundation.org/2006/09/thanks_nick.html%|%Thanks Nick], Graham Barr, 2006-09: [AMG]: Not to take anything away from Nick, but the linked article and its comments attribute the development of [Tk] itself to Nick. Sample quote: "Tk was initially born out of frustration that perl didn't have a native GUI at the time. Nick tirelessly developed Tk for over a decade." [Tcl] isn't mentioned even once in the article or its comments. I guess the charitable interpretation is that "Tk" is meant as the name of the [Perl] module which he did develop, not the like-named GUI toolkit with which it interfaces. [PYK] 2014-04-02: According to the [Perl] page, though, he did actually hack on Tk itself quite a bit, producing a fork that didn't require Tcl, which was then used by [Perl/Tk]. <> Person
