Josephine Countess von Clary-Aldringen (d. 1828) was married to Christian-Christoph Count Clam-Gallas, the famous musical patron of Prague. She was a well-known amateur singer for whom Beethoven wrote the scena "Ah, perfido" in 1796.
A signed version of the present miniature, from the collection of Countess Clothilde Clam-Gallas, Vienna, is illustrated in H. C. Robbins Landon, Beethoven, London, 1970, p. 53 fig. 37.
