Heinrich von Bünau
After studying at the University of Leipzig, Bünau entered the service of the Electors of Saxony and became an assessor in the Upper Court (Oberhofgericht) at Leipzig. Later he became Senior Consistory President and Privy Councillor (Wirklicher Geheimrat).
He received advancement through the good offices of the Cabinet Minister of the Electors of Saxony, Count von Hoym, the uncle of his second wife. In 1734, after Hoym had been ousted by Count Brühl, Heinrich von Bünau was downgraded to the position of Senior Overseer of the County of Mansfeld in Eisleben.
In 1741 however he entered the service of the Emperor Charles VII, who made him an Imperial Privy Councillor (Reichshofrat), the first Protestant to fill that role, and employed him as an ambassador in the area of Upper and Lower Saxony. In 1745, after the death of the emperor, Bünau withdrew to his estate at Nöthnitz near Dresden to pursue his scientific and historical studies.
In 1751 Bünau was appointed as Guardian Governor of the Duchy of Saxe-Eisenach, during the minority of Duke Constantin, for whom in 1756 he became Prime Minister in Weimar. In 1759, after the death of the Duke, he retired and spent the evening of his life on his estate at Ossmannstedt, near Weimar, where he died on 7 April 1762.
Bünau's private library comprised some 42,000 volumes. It was housed at first in Dresden, then on his estate at Nöthnitz, and he allowed public access to it. The archaeologist Johann Joachim Winckelmann from Stendal worked at Nöthnitz between 1748 and 1754 as Bünau's secretary.

- The Bünau family's website states that by a "private ordinance" the family had obliged its men to use only the forenames Günther, Heinrich, and Rudolph, which is why within this very extended family there are numerous men with the name "Heinrich von Bünau". This has often led to confusion between them in previous research: for example, in the history of the Saxon state, Heinrich, Count of Bünau, has often been confused with his father of the same name, who was Chancellor at the Court of Dresden.
- Apart from the estates of Nöthnitz, Dahlen, and Ossmannstedt already mentioned, Bünau also owned those of Domsen, Göllnitz and Gross-Tauschwitz.
- His house at Ossmannstedt was used for a few years after his death as a summer house by the Duchess Anna Amalia of Saxe-Weimar-Eisenach and her sons. It was bought in 1797 by Christoph Martin Wieland. It is now known as the Wielandgut and contains the Wieland Museum.
