The Fleischner Society is a interdisciplinary learned society with the key aim to advance the study of pathologies of the chest by the use of thoracic imaging.
Eight radiologists congregated in November 1969 to found a new society to advance the knowledge of diseases of the chest, predominantly by the use of thoracic imaging. The radiologists were Robert Fraser, Leo Rigler, Benjamin Felson, George Simon, Norman Blank, Richard Greenspan, Eric Milne, and Morris Simon. Originally Felix Fleischner (1893-1969) was also due to attend, but unfortunately had suffered a fatal myocardial infarction three months earlier. In honor of their friend and colleague, the group decided to call the new organization the Fleischner Society.
Fleischner himself was a distinguished chest radiologist who initially was a Professor of Radiology in Vienna but spent his later life as a Professor of Radiology at Harvard before passing away in 1969.
It was decided from the outset that the membership of the Society would be restricted to invite-only with a maximum of ~70 members. The specialist-members would be drawn from all relevant disciplines, including adult and pediatric chest medicine, anesthetics, radiology, surgery, pathology, and physiology, and be international in scope.
The Fleischner Society is best known in the wider medical world for its published guidelines, which have become the de facto standard for best practice in chest radiology and related fields.
