Stanley Davidson was born in Sri Lanka and began his medical undergraduate training at Trinity College, Cambridge; this was interrupted by World War I and later resumed in Edinburgh. He was seriously wounded in battle, and the carnage and shocking waste of young life that he encountered at that time had a profound effect on his subsequent attitudes and values. mebooksfree.com mebooksfree.comIn 1930 Stanleymebooksfree.com Davidson was appointed Professor of Medicinemebooksfree.com at the University of Aberdeen, one of the first full-time Chairs of Medicine anywhere and the first in Scotland. In 1938 he took up the Chair of Medicine at Edinburgh and was to remain in this post until retirement in 1959. He was a renowned educator and a particularly gifted teacher at the bedside, where he taught that everything had to be questioned and explained. He himself gave most of the systematic lectures in Medicine, which were made available as typewritten notes that emphasised the essentials and far surpassed any textbook available at the time. Principles and Practice of Medicine was conceived in the late 1940s with its origins in those lecture notes. The first edition, published in 1952, was a masterpiece of clarity and uniformity of style. It was of modest size and price, but sufficiently comprehensive and up to date to provide students with the mebooksfree.com mebooksfree.commain elements ofmebooksfree.com sound medical practice. Although the formatmebooksfree.com and presentation have seen many changes in 22 subsequent editions, Sir Stanley’s original vision and objectives remain. More than half a century after its first publication, his book continues to inform and educate students, doctors and health professionals all over the world. mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com Davidson’s Principles and Practice of Medicine 23rd Edition Edited by mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com Stuart H Ralston MD, FRCP, FMedSci, FRSE, FFPM(Hon) Arthritis Research UK Professor of Rheumatology, University of Edinburgh; Honorary Consultant Rheumatologist, Western General Hospital, Edinburgh, UK Ian D Penman BSc(Hons), MD, FRCPE Consultant Gastroenterologist, Royal Infirmary of Edinburgh; Honorary Senior Lecturer, University of Edinburgh, UK mebooksfree.comMark WJ Strachan mebooksfree.com mebooksfree.com mebooksfree.com BSc(Hons), MD, FRCPE Consultant Endocrinologist, Metabolic Unit, Western General Hospital, Edinburgh; Honorary Professor, University of Edinburgh, UK Richard P Hobson LLM, PhD, MRCP(UK), FRCPath Consultant Microbiologist, Harrogate and District NHS Foundation Trust; Honorary Senior Lecturer, University of Leeds, UK mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com Illustrations by Robert Britton Edinburgh London New York Oxford Philadelphia St Louis Sydney 2018 mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com mebooksfree.com © 2018 Elsevier Ltd.
