close. He's more intellectual than I, but he read the manuscript and said he liked it. His genius daughter Alex liked it.

I have been blessed by having some outstanding teachers over the years. University High School, Cornell College, and the University of Illinois College of Medicine in Chicago all provided great instruction. Harry Levinson shared his work with organizational diagnosis and intervention. He supervised my third-year psychiatric residency research paper on this topic and allowed me to participate on the faculty of some of his industrial psychiatry seminars at Menninger's. I can still recite Karl Menninger's lectures verbatim. In addition to being my "ego-ideal" during training, Karl Menninger took the time and made the effort to write to me and to send me books and articles while I was in Vietnam. His grandson, Karl Menninger II, was very helpful in obtaining permission to print excerpts of those letters in this book.

I arrived at writing this particular book through the coaching of my literary agent, Bert Krages. Bert held my hand throughout the process and patiently put up with my insecurities. Harry Harlow reared baby monkeys with substitute wire or terry cloth-covered substitute mothers. When frightened, the baby monkeys would press a lever to get a look at their substitute maternal figures and acquire some security. I compulsively e-mailed Bert, my wire- monkey mama, for the security of knowing that he was there. This has been my first serious effort to put together a book. I had no idea how much work it was going to be or how much time it would take when I began. Bert said that I should not expect the immediate results I was accustomed to seeing in the practice of psychiatry and offered to send me a tranquilizer! I felt as though I had been working on this book for years and was surprised to discover that Bert made his suggestion about a book on Vietnam in February 2002 (of course, I had spent a couple of years in the 1970s putting together the original book on division psychiatry).

I want to thank Mary Lenn Dixon, editor-in-chief; Cynthia Lindlof, copy editor; Wendy Lawrence, Janet Mathewson, Diana Vance, Gayla Christiansen, and all the rest of the Texas A&M University Press publishing team who have been very kind to an old novice writer.

Mary Lenn put me in touch with Dale Wilson, who is a wounded Vietnam vet, retired military history professor at West Point, and
