The young Czernin and certainly his sister were in connection with Wolfgang Amadeus Mozart (and almost the same age), who wrote a violin and piano concerto for them.
[4] In 1781 Czernin married Theresa Schönborn and traveled with her to Italy, Switzerland, France, Belgium, Holland, and England, and became interested in the new fashion of the English landscape garden.
[6] In 1810 Johann Wolfgang von Goethe was invited to Krásný Dvůr Castle, the family estates, near Karlsbad.
[7] In the meantime, Czernin began to accumulate paintings and drawings, and had twenty years later, the most important collection of the Austrian Empire.
[8] From 1817 until 1825 František Tkadlík was the court painter for the Czernin family and appointed as the guard of their art gallery in Vienna.
