The idea for Essentials was originally conceived in the mid-1980s by Holly Smith and by Fred Plum. At the time, Charles C.J. (Chuck) Carpenter and I were Consulting Editors for The Cecil Textbook of Medicine for Infectious Diseases and Nephrology, respectively. Holly and Fred entrained the two of us into participating in a new venture that, happily, has become a successful force in Internal Medicine. The entire idea was to make Internal Medicine accessible in a compact but critical format to medical students, residents, and other practitioners of medicine. It is a privilege to pay tribute to Holly and Fred by dedicating this ninth edition of Essentials to them. Lloyd H. Smith, Jr., MD Dr. Smith, universally known as Holly Smith, is one of the true giants of academic medicine. A thoroughly engaging and courtly Southern gentleman, Holly was educated at Washington and Lee University, where he received a bachelor’s degree, summa cum laude, in 1944. He then went north to Harvard Medical School where, in 1948, he received his MD, magna cum laude. Following his residency in internal medicine at the Massachusetts General Hospital, Holly joined the Army Medical Corps where he provided, among other clinical activities, early dialysis in soldiers afflicted with epidemic hemorrhagic fever in the Korean Conflict. Investigatively, Holly’s work was an exemplar for the early beginnings of molecular biology. In particular, he found that there was a double enzyme defect in a rare genetic disorder, orotic aciduria. Subsequently, working with Hibbard Williams, he discovered the enzyme defects of two distinct forms of primary hyperoxaluria. One can see from the above narrative that Holly excelled in clinical medicine and in research. But perhaps his most powerful impact on internal medicine was his acceptance of the position as chair of internal medicine at the University of California, San Francisco, which he held from 1964 through 1985. He is now a professor of medicine and associate dean emeritus at UCSF. Holly’s contribution as chair of internal medicine at UCSF was, in a word, dazzling. He developed a faculty that is peerless among departments of internal medicine in the United States. Following his tenure as chair of internal medicine at UCSF, Holly became associate dean, a position he held between 1985 and 2000, where his exceptional administrative talents provided a major impetus to the further expansion of UCSF. For his contributions, Holly has been recognized as the president of virtually all the major societies in internal medicine, including the American Society for Clinical Investigation (1969), the Association of American Physicians (1975), and the Association of Professors of Medicine (1978). He has received the George M. Kober Medal from the Association of American Physicians, as well as membership in the American Academy of Arts and Sciences and the Institute of Medicine of the National Academy of Sciences. Fred Plum, MD (Deceased) Fred Plum, attending neurologist at New York Presbyterian Hospital and university professor at Weill Medical College of Cornell University, was, together with Holly Smith, one of the two progenitors of Essentials. Fred was a truly remarkable individual who had an exceptional mastery of the neurologic sciences, both basic and clinical. One could hardly imagine two more different personalities than Holly and Fred. As I mentioned above, Holly is a classic Southern gentleman. Fred was born and raised in Atlantic City, New Jersey, and carried with him the charming but demanding characteristics of a resident of that city. Fred trained in medicine and neurology at New York Hospital and at the neurologic division of Bellevue Hospital. Subsequently, he became an instructor in medicine at Cornell University Medical College, then an assistant professor, associate professor, and professor of medicine (neurology) at the University of Washington School of Medicine, all between 1953 and 1963. In 1963, Fred became the Anne Parrish Titzell Professor and Chair of the Department of Neurology at Cornell University Medical College, a position he held for 31 years. After stepping down as chairman of neurology, he was recognized for his remarkable accomplishments by having been made a university professor at Weill Medical College of Cornell University in 1998. Fred was a member of virtually all distinguished societies in internal medicine and in neurology. He held honorary doctorates from at least two medical schools, including the Karolinska Institute in Stockholm. Fred was not only a spectacular clinician but an extraordinary teacher. His textbook, Diagnosis of Stupor and Coma, written together with J.B. Posner, is one of the classics of its field. Fred, like Holly, recognized in the mid-1980s the need for providing a textbook which was sufficiently concise yet comprehensive to be usable by students, house staff, young physicians, and physicians outside his own discipline of neurology. I remember particularly well the editorial meetings in the early years of Essentials, involving Fred, Holly Smith, Chuck Carpenter, and myself. Fred’s exceptional analytic reasoning, coupled with remarkable flexibility, was clearly a tutorial in how one deals with a pleomorphic group such as the four editors: flexibility on the one hand and an insistence on excellence on the other. Holly and Fred were the two prime movers in the development of what was originally Cecil Essentials of Medicine and is now titled Andreoli and Carpenter’s Cecil Essentials of Medicine. Medical students, residents in internal medicine, young physicians, and others interested in internal medicine owe a great deal to Holly and Fred for their vision in generating the notion of Essentials. And the other editors of Essentials owe Holly and Fred a great debt for tutoring us in how one assembles a textbook of internal medicine. Thomas E. Andreoli, MD (Deceased) Ivor J.
