Siegfried Sudhaus (9 July 1863 in Treptow an der Rega – 22 October 1914 near Bixschoote, Belgium) was a German classical philologist, known for his scholarly treatment of Menander and Philodemus.
He studied classical philology at the universities of Bonn and Berlin, and from 1892 worked as a schoolteacher at the municipal gymnasium in Bonn. In 1898 he received his habilitation for classical philology, and afterwards, by way of a travel scholarship from the Deutsches Archäologisches Institut, he embarked on a study trip to Greece.[1] In 1901 he was named a professor of classical philology at the University of Kiel, where in 1912/13 he served as academic rector.[2] Among his better known students at Kiel was papyrologist Christian Cornelius Jensen.[3] As a volunteer in World War I, he died on 22 October 1914 near the town of Bixschoote in Flanders (First Battle of Ypres).[4]
