This book has been several years in the making. Originally we envisioned it as a collection of letters and unpublished monographs from the Rothbard Papers at the Mises Institute. It was only in 2020 that we realized that a coherent narrative was needed to organize and bring to life the mass of correspondence and other writings. Over the next several years we wrote the manuscript and revised it as suggestions were made and new archival material was discovered.
