Henry Ingersoll Bowditch: The Prominent Physician Who Introduced Thorax Examination and Trocar Thoracentesis in the United States of America.

Born in a wealthy family with a tradition in science, Henry Ingersoll Bowditch (1808-1882) with studies at Harvard Medical School and in Europe had succeeded in leaving his mark in the American history of medicine. He had been a pioneer in the stethoscope's use, which was promoted and suggested to all physicians of his era. He had widely used thoracentesis, an ancient procedure, for pleuritic effusions, diagnosed with a stethoscope. Inside his most popular treatise "The Young Stethoscopist," he had given a plethora of data concerning the auscultation of the lungs, heart, and vessels; obstetrics; and veterinary. To help younger physicians, he demonstrated through figures local anatomy and positions for auscultation, providing information for various types of stethoscopes being in use during the mid-19th century. He was a humanist and reformer for public hygiene. This historical vignette aims to present Henry Ingersoll Bowditch and his work concerning the thorax. For his contributions to education and public hygiene, he should be celebrated as one of the most important figures of the eve of American medicine.
