Emerald is a distributed, object-oriented programming language developed in the 1980s by Andrew P. Black, Norman C. Hutchinson, Eric B. Jul, and Henry M. Levy, in the Department of Computer Science at the University of Washington.[1]

A simple Emerald program can create an object and move it around the system:

const Kilroy ←  object Kilroy   process   const origin ←  locate self   const up ← origin.getActiveNodes   for e in up    const there ← e.getTheNode    move self to there   end for   move self to origin   end process end Kilroy 

Emerald was designed to support high performance distribution, location, and high performance of objects, to simplify distributed programming, to exploit information hiding, and to be a small language.
