Handbuch der Geschichte der Medizin. Begründet von Theodore Puschmann. Herausgegeben von Max Neuburger und Julius Pagel. 3 vols.

Puschmann died before the completion of this work, and it was then edited by Pagel and Neuburger. It ranks with the work of Haeser; many authorities collaborated in the writing of the histories of the various subjects treated. Digital facsimile from the Internet Archive at this link.
