Johann Adolf, Prince of Schwarzenberg
Johann Adolf of Schwarzenberg (20 September 1615, Wermelskirchen – 26 May 1683, Laxenburg) was the first Prince of Schwarzenberg. A diplomat in the service of the Habsburgs, he was a member of the prestigious House of Schwarzenberg.

Biography
Johann Adolf of Schwarzenberg was born on 20 September 1615 in Wermelskirchen, then part of the Holy Empire. He was the son of Adam, Count of Schwarzenberg and Margareta von Palant.

A shrewd diplomat, he first served in Vienna, before entering the service of Archduke Leopold Wilhelm of Austria, then Governor General of the Spanish Netherlands, of which he became chamberlain. He then lived in Brussels at the court of the Archduke. Johann Adolf was a very cultured and polyglot man, familiar with classical literature and a great patron of art. Over time, he collected a rich collection of works of art, which he passed on to his descendants.
He was highly appreciated by Archduke Leopold Wilhelm of Austria and appointed Knight of the Golden Fleece in 1650.

After the latter's death in 1662, Johann Adolf of Schwarzenberg settled permanently in Bohemia, thus acquiring the domains of Wittingau in 1660 and Frauenberg in 1661.

Johann Adolf was a good manager. He contributed a lot in improving the lands he owned, by for example, introducing new crops or supporting the development of crafts. Devout, he sought to help the poorest by founding, among other things, a refuge for the poor.

On 14 July 1670, Emperor Leopold I made him Prince of Schwarzenberg.

He died on 26 May 1683 in his sixty-seventh year in Laxenburg, Austria.

Marriage and descendants
On 15 March 1644, he married in Vienna Marie-Justine de Starhemberg (1608–1681), daughter of Ludwig von Starhemberg  (1564-1620). 
They had six children:
