Walter Albert Ferdinand Brunn (2 September 1876, in Göttingen – 21 December 1952, in Leipzig) was a German surgeon and historian of medicine.
He studied medicine at the universities of Göttingen and Rostock, where he was a student of Carl Garré.
As a hospital physician during World War I, he lost an arm as the result of a septic infection, thus ending his career as a surgeon.

[2][3] From 1934 to 1950 he was director of the Karl Sudhoff-Institut für Geschichte der Medizin und der Naturwissenschaften (Karl Sudhoff Institute for the History of Medicine and Natural Sciences) at Leipzig.
