In the annals of history, a figure sometimes emerges who, though not universally known, is nonetheless of crucial significance. Such a figure was William Phelps Eno, the founder of the Eno Transportation Foundation. This book examines Mr. Eno’s personal background and the organization he created to deal with the centuries-old problem of urban traffic chaos. It highlights the enthusiasm and imagination of this unique man who devoted his adult life and personal fortune to improving transportation for everyone. It also provides a sweeping picture of modern transportation development. John A. Montgomery, 199 pp., 1988.
