Margaret Turner-Warwick, DBE, DM, PhD, is a very appropriate choice as a Giant in Chest Medicine as she has had a major influence on research and understanding of pulmonary disease over a long period. She was born in London in 1924 and is related to Lord Baden-Powell, the founder of the Boy Scout movement. She studied physiology at Oxford University and qualified in medicine at University College Hospital in London in 1950. During the same year, she married Richard Turner-Warwick, who she met in Oxford and who went on to become a distinguished urologic surgeon. After junior medical posts in London, she decided on a career in respiratory medicine after working at the Brompton Hospital, then as now the major respiratory center in the United Kingdom.
