American Thoracic Society

The American Thoracic Society’s mission is to improve health worldwide by advancing research, clinical care, and public health in respiratory disease, critical illness, and sleep disorders. Founded in 1905 to combat tuberculosis, the ATS is the world’s oldest respiratory society. While the scope of the Society’s activities have expanded greatly, its founding philosophy–that disease is vanquished faster when knowledge is shared–remains a touchstone for its programs and people, including 15,000 members.
