Wilhelm Busch (surgeon)
Karl David Wilhelm Busch (5 January 1826 in Marburg – 24 November 1881 in Bonn) was a German surgeon.

Biography
He was born in Marburg, and studied at the University of Berlin, where he was a student of Johannes Peter Müller and Bernhard von Langenbeck. He received his doctorate in 1848. In 1855, he was appointed professor of surgery at Bonn, and afterwards acted as consulting surgeon general in the army in 1866 and during the Franco-Prussian War. In 1866 Busch observed that erysipelas infections could reduce tumor sizes in patients; in 1867 he induced an erysipelas infection in a patient and the patient's tumor vanished.  In 1867 he became director of the Surgical Clinic of the University of Bonn (), the world's first in cancer immunotherapy. Among his students at Bonn was dermatologist Joseph Doutrelepont.
