Editing Josip Plemelj (section)

== Life ==
Plemelj was born in the village of [[Bled]] near [[Bled Castle]] in [[Austria-Hungary]] (now [[Slovenia]]); he died in [[Ljubljana]], [[Socialist Federal Republic of Yugoslavia|Yugoslavia]] (now Slovenia). His father, Urban, a [[carpenter]] and [[croft (land)|crofter]], died when Josip was only a year old. His mother Marija, née {{not typo|Mrak}}, found bringing up the family alone very hard, but she was able to send her son to school in Ljubljana, where Plemelj studied from 1886 to 1894. Due to a bench thrown into [[Tivoli Pond]] by him or his friends, he could not attend the school after he finished the fourth class and had to pass the final exam privately.<ref>{{cite journal |url=http://www.presek.si/33/1625-Juznic-Prosen.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.presek.si/33/1625-Juznic-Prosen.pdf |archive-date=2022-10-09 |url-status=live |title=Profesor Plemelj in komet 1847 I |language=sl |trans-title=Professor Plemelj and Comet 1847 I |author=Južnič, Stanislav |author2=Prosen, Marjan |journal=Presek: List za Mlade Matematike, Fizike, Astronome in Računalnikarje |volume=33 |issue=3 |year=2005–2006 |pages=26–28 |issn=0351-6652}}</ref> After leaving and obtaining the necessary examination results he went to the [[University of Vienna]] in 1894 where he had applied to Faculty of Arts to study [[mathematics]], [[physics]] and [[astronomy]]. His professors in Vienna were [[Gustav Ritter von Escherich|von Escherich]] for [[mathematical analysis]], [[Leopold Bernhard Gegenbauer|Gegenbauer]] and [[Franz Mertens|Mertens]] for [[arithmetic]] and [[algebra]], [[Edmund Weiss|Weiss]] for astronomy, [[Joseph Stefan|Stefan]]'s student [[Ludwig Boltzmann|Boltzmann]] for physics.

In May 1898, Plemelj presented his [[Doctor of Philosophy|doctoral]] thesis under Escherich's tutelage entitled ''Über lineare homogene Differentialgleichungen mit eindeutigen periodischen Koeffizienten'' (Linear Homogeneous Differential Equations with Uniform Periodical Coefficients). He continued with his study in [[Berlin]] (1899/1900) under the German mathematicians [[Ferdinand Georg Frobenius|Frobenius]] and [[Lazarus Immanuel Fuchs|Fuchs]] and in [[Göttingen]] (1900/1901) under [[Felix Klein|Klein]] and [[David Hilbert|Hilbert]].

In April 1902 he became a private senior lecturer at the University of Vienna. In 1906, he was appointed assistant at the [[Technical University of Vienna]]. In 1907, he became associate professor and in 1908 full professor of mathematics at the [[Chernivtsi University|University of Chernivtsi]] ([[Ukrainian language|Ukrainian]]: Чернівці, [[Russian language|Russian]]: Черновцы), [[Ukraine]]. From 1912 to 1913 he was dean of this faculty. In 1917, his political views led him to be forcibly ejected by the government and resettled  in [[Moravia]]. After the [[World War I|First World War]] he became a member of the University Commission under the Slovene Provincial Government and helped establish the first Slovene university at Ljubljana, and was elected its first chancellor. In the same year he was appointed professor of mathematics at the Faculty of Arts. After the [[Second World War]] he joined the Faculty of Natural Science and Technology (FNT). He retired in 1957 after having lectured in mathematics for 40 years.
