Chevalier Jackson: the father of American bronchoesophagoscopy.

Chevalier Jackson was involved with bronchoesophagoscopy from the late 1800s until shortly before his death in 1958. A pioneer in the field, he developed numerous instruments used in peroral endoscopy and taught their safe and effective use. Most of the next generation of leaders in the field of bronchoesophagoscopy were trained in his clinics in Pittsburgh and in Philadelphia, where he held academic appointments at the six leading medical institutions of these cities. He was a keen observer, inventor, prolific writer, and humanitarian.
