A painting can have an impressive pedigree and still find itself stranded.
Katze in Blumenwiese came directly from the estate of Ernst Ludwig Kirchner and carried the estate stamp on its reverse. Those facts gave it a strong connection to one of the central figures of German Expressionism. Yet the painting had spent decades attached to another artist’s name.
A Swiss collection acquired it in 1980 as a work by Albert Müller, a younger Swiss painter who knew Kirchner and worked within his orbit. Specialists later rejected that attribution. Müller was out, but Kirchner had yet to be formally confirmed. The painting was left without a secure author.
This mattered far beyond the wording on a label. A Kirchner attribution requires acceptance by the Kirchner Archive and, ultimately, a place in the artist’s catalogue raisonné. Without that recognition, a gallery may believe in the painting and scholars may argue in its favour, yet the work remains difficult to sell.
In 2008, the Swiss Institute for Art History convened a symposium devoted to the case. Around a dozen leading Kirchner specialists examined the painting. A substantial majority considered it authentic. Even this gathering failed to close the matter. The Kirchner Archive had yet to issue the formal opinion the market required.
The stalemate lasted for years.
Art Recognition entered the case in 2022. Its model had been trained on authenticated works by Kirchner and tested the painting against the visual habits found across his accepted body of work. The analysis returned a 97.3 per cent probability in favour of Kirchner’s authorship.
That result gave the Kirchner Archive another substantial piece of evidence to consider. The Archive subsequently issued a certificate, confirming Katze in Blumenwiese as an authentic work by Ernst Ludwig Kirchner.
Galerie WOS described the outcome directly: “Based on the examination by Art Recognition, we have now received the certificate from the Kirchner Archive for the painting Katze in der Blumenwiese.”
The painting has since returned to public view, including an appearance at Art Karlsruhe in February 2026. It can also enter the market under Kirchner’s name, with the enormous difference in value and significance that attribution carries.
This case offers a useful picture of what AI analysis can contribute when respected specialists have already studied a work and the formal process has stalled. The model supplied a documented assessment drawn from the painting’s image. The Archive remained responsible for the final expert opinion.
For nearly forty years, Katze in Blumenwiese sat between two names. One had been rejected; the other awaited confirmation. Art Recognition helped provide the evidence that finally allowed the painting to go home.
