René-Théophile-Hyacinthe Laënnec invented the stethoscope in 1816 while trying to examine a young female thought to have a heart problem, improving the diagnosis of disease and establishing objectivity in clinical medicine. This invention came while physicians were struggling to correlate post-mortem pathology with clinical symptoms. Until 1816, symptomatology was the only means to diagnosis. The stethoscope not only connected post-mortem findings with clinical findings but also helped identify illnesses that were asymptomatic. Laennec’s invention furthered the study of physiology, and he used it to study the lung and heart. This paper discusses both his life and his pivotal contribution to medicine.
