Carl J. Wiggers and the pulmonary circulation: a young man in search of excellence

Abstract

Oddly, Carl Wiggers (1883–1962), who is remembered for his work on the systemic circulation, may be considered the “American father of the pulmonary circulation.” In nearly 20 papers published in the American Journal of Physiology between 1909 and 1925, he reported the first reliable pressure contours in the pulmonary artery, inquired into the relationship between respiration and pulmonary arterial pressure, examined right atrial and right ventricular function, and demonstrated how right and left heart dynamics relate to heart sounds. He also stimulated direct visualization of the lung microcirculation. Method and concept are inextricably linked in the progress of science. His contributions to the pulmonary circulation were based on his high-fidelity pressure and sound recording instruments, which he ultimately applied in the left heart. Wiggers’ search for excellence in method brought him well-deserved fame in the systemic circulation, but the search began in the lung.
