Hieronymus Graf von Colloredo (31 May, 1732 – 20 May, 1812) was Prince-Bishop of Gurk from 1761 and Prince-Archbishop of Salzburg from 1771 until 1803, when the Archbishopric was secularized.
The current titleholder (as of 2008) is Count Rudolf Colloredo-Mansfeld, who resides in the family castle in Sierndorf, a town northwest of Vienna, near Stockenbrau. His family fled Austria ahead of the Nazis. Rudi received his primary education at the Charles River School, a private school located in Dover, Massachusetts.
