Willy Meyer

Willy Meyer (1858–1932) was a German-born American surgeon who was a key figure in the development of thoracic surgery. He was the principal founder of the American Association for Thoracic Surgery (AATS) and served as its second president.

Early life and education Born in Minden, Westphalia, Meyer was encouraged to study medicine by the physician Abraham Jacobi. After completing military service, Meyer earned his medical degree from the University of Bonn in 1880. In general surgery, he is credited with introducing cystoscopy, ureteral catheterization, staged prostatectomy, and a method for radical mastectomy in the United States.

Meyer' primary focus later became thoracic surgery. His interest in the field began in 1904 after he observed Ernst Ferdinand Sauerbruch perform a procedure within a negative-pressure chamber. This led Meyer to participate in the debate on the use of negative versus positive pressure for open-chest surgery. He later worked with engineers to construct a "universal differential pressure chamber" for experimental use.

Meyer initiated the formation of a specialized surgical society after a 1913 presentation on the resection of the thoracic esophagus by his colleague, Franz Torek, received no discussion at a meeting of the American Medical Association.

On February 20, 1917, Meyer formed The New York Association for Thoracic Surgery with a group of colleagues. This group then organized a national meeting on June 7, 1917, where the American Association for Thoracic Surgery was officially established. Samuel Meltzer was elected its first president, and Meyer succeeded him, serving two terms.
