Dr Thomas L. Petty lost his 10-year struggle with cardiac disease and pulmonary hypertension on Saturday, December 12, 2009. Dr Petty’s commitment to continuing medical education and focus on excellence in patient care were among his greatest gifts to the American College of Chest Physicians (ACCP). He was the senior editor of CHEST from 1970-1975 and the President of the ACCP from 1981-1982. In 1995, Dr Petty was elected a Master Fellow, the ACCP’s highest honor. In 2007, as a special tribute to him, The CHEST Foundation established the Thomas L. Petty, MD, Master FCCP Endowment in Lung Research. At this event, hundreds of colleagues, friends, and associates personally thanked Dr Petty for his lifetime commitment to the education of physicians, other health-care workers, and patients with pulmonary disease.
