Count Friedrich August von Harrach-Rohrau, (Vienna, June 8, 1696 – Vienna, June 4, 1749), was plenipotentiary minister of the Austrian Netherlands (1732–1741) and became Governor-General ad interim in 1741–1744.
:Count Harrach ... was the first to bring the music of Sammartini to Vienna, where it quickly won applause and became the vogue in that great capital so enamored of this kind of diversion.
In 1744 he had married Maria Josepha, Countess of Harrach-Rohrau (20 November 1727 – 15 February 1788), daughter of Count Friedrich August von Harrach-Rohrau.
The former German Junker (landed nobility) of the Harrach family left a Baroque palace that is now property of Count Ghislain de Nicolay.
