7723 Lugger           Discovered 1952 Aug. 28 at the Goethe Link Observatory, Indiana University.
Phyllis Lugger (b. 1954), on the faculty of Indiana University, is known for her work on the luminosity functions of galaxies in clusters and on the dynamics of globular clusters and stellar systems, including the Milky Way galaxy and interacting binary stars. She has also worked on the identification of x-ray sources.
