DESMO-J has been developed at University of Hamburg's research group of Modelling and Simulation.
First released in 1999, the environment continues to be maintained and kept up to date, now in terms of a SourceForge Project.
DESMO-J's predecessor was DESMO, a Modula-2-based simulation library, which in turn was inspired by DEMOS, a system for discrete event modelling on Simula.

A companion book has appeared 2005.
