|This website documents the history of the Emerald programming language.
Emerald is a distributed, object-oriented programming language that was developed at the University of Washington starting in 1984. The goal of Emerald was to simplify the construction of distributed applications. This goal was reflected at every level of the system: its object structure, the programming language design, the compiler implementation, and the run-time support.
A short Emerald program (affectionately know as “Kilroy was here”) is shown on the right.
