Joseph Nicholas of Windisch-Graetz

Joseph Louis Nicholas, Count of Windisch-Graetz, Baron of Waldstein and Thal (6 December 1744 – 24 January 1802 in Štěkeň) was a nobleman, a member of the House of Windisch-Graetz, and was chamberlain to Archduchess Marie Antoinette of Austria. He was the second son of Count Leopold Carl Joseph of Windish-Graetz (1718–1746) and his wife Countess Maria Antonia Josepha von Khevenhüller (1726–1746).

Family archive
On 12 May 1781, he purchased the lordships of Tachov, Ctěnice, and Štěkeň from Ernestine Fuchs von Bimbach, the widow of Count Adam Philipp Losy von Losinthal. Here he founded his extensive family archive. His descendants later moved this archive to the former Kladruby monastery, which they had acquired after it had been secularized.
