PLT is the name of a research group that I founded at Rice University 
some 15 odd years ago. Initially our research focus was pl theory with 
an eye toward use in FP. Corky Cartwright a prof at Rice worked with us 
too at that time. In the mid 1990s, I proposed to focus on 
FP/Scheme/programming environments for education. You may want to look 
at a talk called From POPL to the Classroom and Back, available off my 
web site.

Matthew took the lead with the integration of 14 (that's a vague 
memory) packages and languages and voila` we had MrEd and soon a 
DrScheme-like thing (version # in the upper 20s low 30s). I taught with 
the thing, but none of the teachers from this first workshop survived 
:-) Cormac Flanagan and Shriram added things to the package and before 
we knew it we had a visual, static debugger and could get funding for 
it. The MrEd number was in the low 40s, soon in the upper 40s. Robby 
Findler joined and took over the drscheme part because it had grown 
very large.

I take it you know the rest of drscheme.

For the logos from all these years, see
