Katharina Fröhlich

Katharina "Kathie" Fröhlich (10 June 1800 – 3 March 1879) was engaged to Franz Grillparzer for 50 years.

[2] In 1849 Grillparzer rented an apartment with Katharina Fröhlich and her sisters Anna, Josephine and Barbara in Vienna at Spiegelgasse 21.

Grillparzer, who never made good his promise to marry Katharina Fröhlich, bequeathed his entire estate to the sisters.

In 1928/1929 a residential complex was built in Vienna's Malfattigasse, 149 apartments, and named Fröhlichhof in honor of Katharina Fröhlich.

The Fröhlich sisters' possessions and Grillparzer's original room can be visited in the Vienna Wien Museum.
