Count Hieronymus von Colloredo, Austrian archbishop (d. 1812)
Hieronymus Joseph Franz de Paula Graf Colloredo von Wallsee und Melz (Jérôme Joseph Franz de Paula, Count of Colloredo-Wallsee and Mels; 31 May 1732 – 20 May 1812) was Prince-Bishop of Gurk from 1761 to 1772 and Prince-Archbishop of Salzburg from 1772 until 1803, when the prince-archbishopric was secularized. After secularization, Colloredo fled to Vienna and remained the non-resident archbishop of Salzburg, bereft of temporal power, until his death in 1812. He is most famously known as a patron and employer for Mozart.
