Gustav Amberger (1831-1896), a painter and engraver of allegorical subjects and landscapes, was a pupil of Joseph van Lerius in Antwerp and Cornelius in Rome. His jouneys to Sweden and Norway provided him with many landscape subjects. Notable works by him include Leda, painted in Rome and bought by the Empress of Russia, and a distant view of Baden-Baden nestling within wooded hills.

Moonlit view of the monument to Princess Feodore of Hohenlohe-Langenberg in the form of a full-length figure of a woman in a melancholic pose, seated on the stepped pedestal of a tall unadorned cross; set in a wooded cemetery before a chapel. The frame is formed of a classical entablature supported by two composite columns, with creeping foliage.

An edition of the Ilustrated London News of June 1874 carried an engraving after a photograph of this monument, and the following account: 'A monument has been designed by his Serene Highness Count Glucken, Prince Victor of Hohenlohe, to be placed over the grave of his mother, Princess Hohenlohe-Langenburg, sister of Queen Victoria, in the cemetery at Baden-Baden. She died on September 23rd, 1872. The design represents a beautiful female figure, an embodiment of the soul, who is raised at the foot of a large upright cross. The monument being in view, the face of the figure is turned to the charming little villa, two miles distant from the cemetery, in which the Princess resided during many years, and where she breathed her last.'
