His parents, both ethnic Slovenes, did not marry until Josef was eleven. The Stefans were of modest means; his father was a milling assistant and his mother served as a maidservant. Josef was their only child.<ref>{{Cite web|last=Čermelj, L., Uršič, M.|title=Jožef Stefan|url=http://www.slovenska-biografija.si/oseba/sbi605384/#slovenski-biografski-leksikon|website=lexicon of slovenian biographies}}</ref>
