History of the American Astronomical Society

This history was a project of the Historical Astronomy Division of the American Astronomical Society and was kindly sponsored by the Society in preparation for its Centennial Year in 1999. The project was developed by Brant L. Sponberg and David H. DeVorkin, and formed the basis for many of the articles and essays in DeVorkin, D., ed., The American Astronomical Society's First Century (AIP: AAS, 1999).
