Oppenheim studied at the Städelschule in Frankfurt and from 24 April 1894 at the Academy in Munich.
The "aryanization" of his collection was carried out in 1943 by Ernst Holzinger, the director of the Städel Museum, who did not auction them, but sought to incorporate them into the city's possessions.

Although Alfred Oppenheim was successful as an artist, for example as a portraitist of the Frankfurt bourgeoisie, he had further activities.
Educated in Paris as a jeweler, he worked in the style of French Art Nouveau, which was an exception in Germany at that time, although he is more associated with German impressionism.
