Carl Johann Christian Zimmermann

He initially studied art history at the University of Königsberg, passed the surveyor's examination and was involved in building a section of the Prussian Eastern Railway.

His projects during that time included the Museum für Kunst und Gewerbe (1873–76), the Fuhlsbüttel Central Prison [de], the Wilhelm-Gymnasium (1883–85), and the University Medical Center Hamburg-Eppendorf (1884–89), among others.
