NO RELEASES AVAILABLE WITH PHOTOGRAPHER René-Théophile-Hyacinthe Laennec (February 17, 1781 – August 13, 1826) was a French physician. He invented the stethoscope in 1816, while working at the Hôpital Necker and pioneered its use in diagnosing various chest conditions. He became a lecturer at the Collège de France in 1822 and professor of medicine in 1823. His final appointments were that of Head of the Medical Clinic at the Hôpital de la Charité and Professor at the Collège de France. He died of tuberculosis in 1826. Laennec had discovered that the new stethoscope was superior to the normally used method of placing the ear over the chest, particularly if the patient was overweight. A stethoscope also avoided the embarrassment of placing the ear against the chest of a woman. Laennec is said to have seen schoolchildren playing with long, hollow sticks in the days leading up to his innovation. The children held their ear to one end of the stick while the opposite end was scratched with a pin, the stick transmitted and amplified the scratch. His skill as a flautist may also have inspired him. He built his first instrument as a 25 cm by 2.5 cm hollow wooden cylinder, which he later refined to comprise three detachable parts.
