Named in honor of John S. Gallagher III, director of Lowell Observatory. Gallagher’s particular devotion to astronomy has been manifest in his service to the community, energetic and productive research, and teaching. He is a council member of the American Astronomical Society, is an editor of the Astrophysical Journal and has served on numerous committees and boards. His research has included work on luminous stars, novae, a broad variety of extragalactic problems, and cosmology. With a colleague, he discovered the ultraviolet output of novae and developed a method to evaluate star-formation rates at different stages in the evolution of galaxies. (M 12807) _ _.
