In memory of Pearl Schwartz and Sol Schwartz, for their unconditional love and for providing the foundation, early confidence, encouragement, and support during my formative years. I miss both of you. In memory of my biological father, Harry S. Taylor, for providing the seeds and support for my education, and for the genetics and heritage of the Taylor family.
To my four adult children—Angie, Ian, Cindi, and David—their wonderful spouses, and my three grandchildren: my endless love, gratitude, understanding, and congratulations for all your accomplishments and the many joys you bring to me. You all continue to provide meaning and inspiration.
To Nancy M. Schwartz, for the joy she brings to her family and friends, and for her humor and infectious laughter. It is easy to love her. To her sons, for their great wit, their love and devotion to their mother, and their many talents. And to Nancy's wonderful parents, for continued life inspirations.
To the same professionals listed in the first and second editions, my thanks. And again to Donn Byrne, PhD, whose retirement Festschrift in April 2002 reminded me of how he inspired me and of my gratitude for his mentoring. To those authors from the two previous editions who did not write chapters for this new edition, I again thank you for your contributions that helped make those prior editions successful, hence allowing a third edition. And to all those professionals who reviewed the prior editions, for their thoughtful reviews. Finally, in memory, again, of Susan P. Lowery, for whom there is a Memorial Statement in the second edition. Susan was an inspiration to all who knew her.
To the Mayo Clinics and Mayo Foundation, my professional home for over 35 years, for all the reasons noted in the second edition, and to all those of the Mayo Foundation thanked in the first two editions. To Paul A. Fredrickson, MD, and T. Carey Merritt, MD, two very close friends and colleagues. A new thanks to Daniel Hubert, of Mayo Clinic Medical Photography, for help with photographs. To Kathryn Dolan of the legal department of Mayo Foundation, for her patience and skillful help.
Many thanks again to The Guilford Press, for continued acceptance, support, patience, and flexibility. Thank you, Seymour Weingarten, Editor-in-Chief, and Robert Matloff, President, for your long-term support and wonderful style. It has always been fun and comfortable working with you. To Carolyn Graham, who charmingly and tactfully managed many of the preproduction administrative matters for the book. To the wonderful copy editor, Marie Sprayberry, who also provided copy editing for the first edition, again my gratitude for your
