A short history of Glamorous Toolkit
Glamorous Toolkit embodies our long term goal of making the inside of software systems explainable. It is the first environment that supports Moldable Development.

See Smalltalk history for a broader perspective.
We could expand this page with a bit of history of Moose, Pharo, and also SmaCC, PetitParser and Magritte, with pointers to literature, blogs etc.
