In February of 1953, Otto Greis – a native of Frankfurt – produced the series "The Functional of Spot and Line" consisting of 75 drawings. In these works, the artist found different ways of having the dot and the line enter into dialogue, always in pursuit of their spatial effect in the process. In each case, he covered a sheet of light-shaded paper with black, red and sulphur-yellow paint, which took on cloudy forms. To these colour zones he added white or red drips, splatters or sweeps. In cases where the water- and oil-based paints repelled one another, these additions formed beads on the surface. Elsewhere, the bright accents stand out from the surface in relief-like manner, introducing a third dimension to the drawing.
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.
