Named in honor of Sally M. MacGillivray of Sky Publishing Corporation. With an early bent for music and philosophy, followed by 20 years' experience in book publishing, she brought to the Millennium Star Atlas (1997) an elegance that is rare in a scientific work and evokes bibliophilic traditions. As publication manager of this collaborative venture with the European Space Agency's Hipparcos project, she masterfully orchestrated the many iterations by two teams of illustrators needed to complete the 1548 charts in the atlas. Name suggested by R. W. Sinnott and endorsed by the discoverer.
