The Städel Museum has the photographer, psychotherapist, philanthropist, and long-time Frankfurt resident Ulrike Crespo (1950–2019) to thank for more than ninety works ranging from classical modernism to American pop art. The paintings, drawings, and prints by Wassily Kandinsky, Otto Dix, Oskar Schlemmer, Max Ernst, Jean Dubuffet, Cy Twombly, and others originally belonged to the holdings of her grandfather, the Darmstadt-based industrialist Karl Ströher (1890–1977), who amassed an extensive art collection after World War II.
Since 2001, the Städel Museum has systematically been researching the provenance of all objects that were acquired during the National Socialist period, or that changed owners or could have changed owners during those years. The basis for this research is the “Washington Declaration”, also known as the “Washington Conference Principles”, formulated at the 1998 “Conference on Holocaust-Era Assets” and the subsequent “Joint Declaration”.
The provenance information is based on the sources researched at the time they were published digitally. However, this information can change at any time when new sources are discovered. Provenance research is therefore a continuous process and one that is updated at regular intervals.
Ideally, the provenance information documents an object’s origins from the time it was created until the date when it found its way into the collection. It contains the following details, provided they are known:
The successive ownership records are separated from each other by a semicolon.
Gaps in the record of a provenance are indicated by the placeholder “…”. Unsupported information is listed in square brackets.
