Augusta Louise zu Stolberg-Stolberg

Countess Louise Augusta zu Stolberg-Stolberg (7 January 1753 in Bramstedt, Duchy of Holstein – 30 May 1835 in Kiel) was a German noble who was known for her lively correspondence with the poet and thinker Johann Wolfgang von Goethe; she is known as Goethes Gustchen in the history of literature.

She was younger sister of Goethe's friends Count Friedrich Leopold zu Stolberg-Stolberg ("Fritz") and Count Christian zu Stolberg-Stolberg.

She lived in a pension for young, unmarried noble girls from 1770 to 1783 along with the older Baroness Metta von Oberg.

"Augusta – vom Morgen bis in Abend laufen die Depeschen bey ihr ein, wie bey einem Staatsminister, und werden sorgfältiger abgefertigt, als in einer Canzelley" noted Friedrich Gottlieb Klopstock.

On 7 August 1783 Augusta Louise moved to Copenhagen, and later married the Danish Minister of State Count Andreas Peter von Bernstorff.
