“Writing this book would ideally require an author with an extensive knowledge of astronomy, including astronomical instruments, a deep understanding of the ways of thought of astronomers, a broad range of historical knowledge, and an exceptional skill at making astronomical ideas clear and engaging. Alan Hirshfeld possesses all of these skills. His Starlight Detectives is remarkable.”

Michael J. Crowe, author of The Extraterrestrial Life Debate, 1750–1900
