"Cockerell speaks to us from not only the frontiers of Colorado and the Victorian era, but also from the spirit of one galvanized by a passion for nature, beauty, and understanding. Today we lament the loss of naturalists as our biota is ravaged. Here Weber has resurrected Cockerell's vivid accounts; perhaps we may learn anew from a master's hand and before our flora and fauna vanishes."
– Dr. Michael S. Engel, Division of Entomology, Natural History Museum, University of Kansas
"In giving us T. D. A. Cockerell up close and personal, William A. Weber has delivered a very valuable and interesting look at a period when science and education on the American frontier were at their earliest stages, and dependent on the heart and vision of an intrepid few." – Edward O. Wilson, University Research Professor Emeritus, Harvard University
"This entertaining collection of letters provides a delightful insight into pioneer days in Colorado and the formative years of one of America's greatest naturalists. Evocative of simpler times-but there was clearly plenty to do then too, and this is a very pleasant way to learn something about it."
– Peter H. Raven, Director, Missouri Botanical Garden, St. Louis
