Viktor Schmieden (19 January 1874 – 11 October 1945) was a German surgeon born in Berlin.
Schmieden is remembered for his work with Franz Volhard (1872-1950) in the establishment of pericardectomy for the treatment of constrictive pericarditis.
Historically this procedure was referred to as "Schmieden's operation".
He also made important contributions towards the treatment of hydrocephalus, and in 1926 identified that polyps of the colon were a precursor of colorectal cancer.
With August Borchard (1864-1940), he was co-author of two books on war-related surgery; Lehrbuch der Kriegschirurgie and Die deutsche Chirurgie im Weltkriege 1914-1918),[1][2] and with Ernst Ferdinand Sauerbruch (1875-1951), he published the sixth edition of Chirurgische Operationslehre (Surgical Operation Teachings) by August Karl Gustav Bier, Heinrich Braun and Hermann Kümmell.
