Albert J. Ochsner was one of that great group— Fenger, Senn, Murphy and Ochner—who made Chicago a surgical center. Their work has been our inspiration. Christian Fenger taught American surgeons the importance of pathology. He was one of the first in this country to remove stones from the common duct, and the first to describe their ball valve action. He developed and perfected operations for the treatment of tuberculosis of the joints and cancer of the stomach. By invitation he presented the results of his investigations on kidney surgery to the International Medical Congress in Paris in 1900. He established the first pathologic laboratory in Cook County Hospital. At his death the character and importance of his work was emphasized by a monument placed in that institution.
Nicholas Senn, as a student, waited on table for his board, and began his record making experiments on intestinal anastomosis with home-made equipment
