Norm Hutchinson  U Washington, early 80's.

A polymorphic object-oriented distributed programming language/environment. Strongly typed, uses signatures and prototypes rather than classes and inheritance.

language and programming system providing both process and object mobility on a network of workstations. Objectives- develop and distribute an OOL and system incorporating lightweight object migration, and investigate the issues in using such languages for distributed application development, particularly the areas of reliability and availability.  

The EMERALD compiler, which is written in EMERALD, generates byte codes which are then interpreted by a relatively portable interpreter. The interpreter takes care of finding remote objects, performing remote invocations, moving objects, and doing both local and distributed garbage collection.
