Named in memory of David Emerson (1943–1996), lecturer in astrophysics at the Royal Observatory, Edinburgh. His research interests were in the interaction of matter and radiation and star formation. He was director of studies of the first discoverer. Emerson was also an ordained lay-preacher in the Scottish Episcopal Church. He died at a relatively young age on 1996 Sept. 26, just a few weeks after the discovery was made. (M 31613) _ _.
