This book is about William Phelps Eno and the organization he created to deal with centuries-old problem of traffic chaos. In a broad sense it also is a chronology of modern transportation development. It reflects the enthusiasm and imagination of one person who devoted most of his life's effort and personal resources to bettering transportation for everyone. While many are acquainted with the Eno Foundation, few know its history or the extent to which it affects their daily lives. That is why this book was developed.
