Milko Kos
Milko Kos (12 December 1892 – 24 March 1972) was a Slovenian historian, considered the father of the Ljubljana school of historiography.
He was born in the town of Gorizia (then part of Austro-Hungarian Empire, now in Italy), where his father, the renowned medievalist Franc Kos, taught at the prestigious State Gymnasium. His mother was a Friulian from Gorizia and Gradisca. His younger brother Anton Gojmir Kos later became a prominent painter.
He studied history at the University of Vienna, specializing in the social history of the middle ages. He was an expert on medieval settlement patterns in the Slovene Lands. He also wrote about the social history of medieval towns and issues related to early Slovenian history, including the Slavic principality of Carantania and the Freising manuscripts.
In 1928, he started teaching at the University of Ljubljana, where he replaced Ljudmil Hauptmann as the head of the chair for Slovene history. In this position, he influenced almost all Slovenian historians of the post-WWII period; most of them graduated under his direct supervision, including Fran Zwitter and Bogo Grafenauer.
