This fascinating portrait of an amateur astronomy movement tells the story of how Charles Olivier recruited a hard-working cadre of citizen scientists to rehabilitate the study of meteors. By 1936, Olivier and members of his American Meteor Society had succeeded in disproving an erroneous idea about meteor showers. Using careful observations, they restored the public’s trust in predictions about periodic showers and renewed respect for meteor astronomy among professional astronomers in the United States. Charles Olivier and his society of observers who were passionate about watching for meteors in the night sky left a major impact on the field. In addition to describing Olivier’s career and describing his struggles with competitive colleagues in a hostile scientific climate, the author provides biographies of some of the scores of women and men of all ages who aided Olivier in making shower observations, from the Leonids and Perseids and others. Half of these amateur volunteers were from 13 to 25 years of age. Their work allowed Olivier and the AMS to contradict the fallacious belief in stationary and long-enduring meteor showers, bringing the theory of their origin into alignment with celestial mechanics. Thanks to Olivier and his collaborators, the study of meteors took a great leap forward in the twentieth century to earn a place as a worthy topic of study among professional astronomers.

In 1966, American historic preservation was transformed by the passage of the National Historic Preservation Act, which created a National Register of Historic Places. Now comprising more than 1.4 million historic properties across the country, the National Register is the official federal list of places in the United States thought to be worthy of preservation. One of the fundamental principles of the National Register is that every property is evaluated according to a standard set of criteria that provide the framework for understanding why a property is significant in American history. The origins of these criteria are important because they provide the threshold for consideration by a broad range of federal preservation programs, from planning for continued adaptive use, to eligibility for grants, and inclusion in heritage tourism and educational programs. Crafting Preservation Criteria sets out these preservation criteria for students, explaining how they got added to the equation, and elucidating the test cases that allowed for their use. From artworks to churches, from 'the fifty year rule' to 'the historic scene', students will learn how places have been historically evaluated to be placed on the National Register, and how the criteria evolved over time.
