Gustav Klimt's portraits tell as much about modern Vienna as the destiny of the people represented. Around the artist, several families of Jewish origin - Bloch-Bauer, Lederer, Gallia, Loew, Munk, Beer or Zuckerkandl - supported the avant-garde. After 1938, their collections experienced very different trajectories: confiscation, sale under duress, flight with works, destruction, restitution or private agreement.
Two shortcuts must therefore be avoided. Klimt was not Jewish, and not all portraits of Jewish sitters were looted. A serious study distinguishes the person who commissions the work, the one who poses, the owner at the time of persecution and the heirs. It then reconstructs each provenance from the archives.
- Sponsor: person who requests and funds the work.
- Model: person represented; she is not necessarily the owner.
- Provenance: documented suite of owners, transfers and places of conservation.
- Spoliation: loss of property under persecution, seizure, forced sale, discriminatory taxation or transfer without genuine freedom of consent.
Why did these families support Klimt?
In Vienna in 1900, the commission of a portrait demonstrated a social position, but also an adherence to modernity. Families enriched by industry, banking or commerce supported artists whom official institutions welcomed with reservation. They frequented salons, arranged their interiors with Josef Hoffmann and collected Klimt, Schiele or other representatives of the avant-garde.
The expression "Jewish patrons" nevertheless covers diverse religious, social and political histories. Some people had converted to Catholicism; Nazi racial laws nevertheless classified them according to ancestry. Their patronage was also exercised in a society marked by anti-Semitism and barriers to access to prestigious positions. To understand this network, we can also read our study of the Viennese secession.
Bloch-Bauer: the order became a matter of restitution
Ferdinand Bloch-Bauer, sugar industrialist, commissioned the first portrait of his wife Adèle in 1903. The work, completed in 1907, was initially to be given to Adèle's parents for their wedding anniversary. It combines gold leaf, geometric patterns and a very individualized presence of the face. Adèle is the only person Klimt has painted twice in full-length portraits.
Adèle requested in her will that Klimt's paintings return to the Austrian Gallery after Ferdinand's death. This request was not a legally binding legacy: the works belonged to Ferdinand. After the Anschluss of 1938, he fled Austria and his property was confiscated. The first portrait entered the Belvedere under a title erasing the model's name.
In 2006, an Austrian arbitral tribunal ordered the return of five Klimts to the Bloch-Bauer heirs, including the two portraits of Adèle. The first was then acquired by Ronald Lauder for the Neue Galerie in New York. Our analysis of the Golden Lady explains its visual language; the folder Maria Altmann and restitution trace the procedure.
Lederer: a collection seized, dispersed and largely destroyed
Serena and August Lederer were among Klimt's most important private collectors. Serena played a leading role: she commissioned her portrait in 1899, then those of her mother Charlotte and her daughter Elisabeth. The family also had landscapes, drawings and Beethoven frieze.
The Lederer collection was placed under Nazi control in 1939. Much of the works stored at Immendorf Castle disappeared in the May 1945 fire. Serena's portrait, seized in Vienna in 1942, was returned to her son Erich in 1948; he entered the Metropolitan Museum of Art in 1980. The portraits of Serena and Elisabeth reappeared at the Dorotheum in 1948 before the sale was abandoned and the works returned to Erich. For this second work, our article on Elisabeth Lederer and her origin details the sources.
Gallia and Beer: two portraits left with their owner
The portrait of Hermine Gallia remember that flight and spoliation are not synonymous. Hermine, born into a Jewish family then converted to Catholicism with her husband, died in 1936. In late 1938 his children left Austria for Australia, taking the painting. The family sold it to Christie's in 1971; today it belongs to the National Gallery in London.
Friederike Maria Beer, the daughter of a Jewish merchant, sat for Klimt in 1916; Hans Böhler financed the commission. After moving to New York around 1934, she founded the Artists’ Gallery and helped émigré artists after 1938. She kept works before selling some in the late 1960s. Klimt’s portrait of her is now at the Tel Aviv Museum of Art: there is no basis for presenting it as a looted painting.
Loew and Munk: fair agreement and municipal restitution
The portrait of Gertrud Loew illustrates another answer. The exact conditions of its acquisition by Gustav Ucicky during the Nazi period could not be fully reconstructed. The Klimt Foundation's research concluded, however, that if the Austrian federal restitution law had been applicable to this private collection, restitution should have been considered. In 2014, the Felsövanyi Foundation and heirs voluntarily entered into an agreement described as fair and equitable under the Washington Principles; the painting was sold at Sotheby's in 2015. It is therefore not a restitution decided by a public museum.
In Linz, the Lentos conducted a provenance search on the Portrait of Ria Munk III, remained unfinished upon Klimt's death. Ria's mother, Aranka Munk, commissioned this memorial effigy after her daughter's death in 1911. The city returned the work to Aranka's heirs in 2009.
Amalie Zuckerkandl: a provenance that resists simple stories
Otto Zuckerkandl commissioned the portrait of his wife Amalie around 1914. Klimt left it unfinished in 1918. The painting was documented by Ferdinand Bloch-Bauer in 1928, but the exact conditions of ownership and transfer to the Müller-Hofmann family remain debated. According to the official notice of 2005, Hermine Müller-Hofmann sold it before 1945 to Vita Künstler, linked to the Neue Galerie in Vienna. Vita and Gustav Künstler donated it to the Belvedere in 1988: this transfer to the museum is distinct from the sale during the Nazi period.
Amalie and her daughter Nora Stiasny were deported and murdered in 1942. Despite this tragic context and a disputed provenance, the Austrian Restitution Council recommended maintaining the painting at the Belvedere. It is therefore incorrect to present it as a case settled by restitution. Our study of unfinished portrait of Amalie Zuckerkandl expand on this timeline.

How are restitutions decided?
Provenance is not reduced to a list of owners. Researchers examine inventories, correspondence, tax records, sales catalogs and legal conditions of transfer. A seemingly regular sale may have been imposed by the persecution. Conversely, a work carried by a family in exile is not automatically a looted work.
In Austria, the 1998 law organizes the restitution of works belonging to the federal state; the Belvedere has since conducted systematic research. Private or municipal collections may fall under other procedures, negotiated agreements or the Washington Principles. To put these cases in context, see our summary at Klimt, Nazi dispossessions and restitutions.

Hermine Gallia is at the National Gallery, Amalie Zuckerkandl at the Belvedere and Friederike Maria Beer at the Tel Aviv Museum of Art.
Frequently asked questions
Was Gustav Klimt Jewish?
No. Klimt came from a Catholic family. Many of its main sponsors and models, however, belonged to Viennese families of Jewish origin.
Why are we talking about Jewish patrons around Klimt?
Families like the Bloch-Bauers, Lederer and Gallia commissioned portraits, collected his works and supported Viennese modernity in a context of social and political anti-Semitism.
Were all the portraits presented despoiled?
No. The Gallia and Beer portraits, for example, left Austria with their owners or were later sold without documented spoliation.
Why didn't Adèle's will settle the Klimt property?
Adèle wanted the works to go to the Austrian Gallery after Ferdinand's death, but the paintings legally belonged to her husband. His request was not a binding bequest.
How many Klimt paintings were returned to the Bloch-Bauer heirs?
Five paintings were returned in 2006: the two portraits of Adèle, Birch Forest, Apple Tree I and Houses in Unterach.
What became of the Lederer collection?
It was placed under Nazi control in 1939. Much of the works stored in Immendorf were destroyed by fire in May 1945; some pieces reappeared and were returned after the war.
Has the portrait of Hermine Gallia been restored?
No. The Gallia children took the portrait to Australia in late 1938. The family sold it in 1971, and it is now owned by the National Gallery in London.
What's a fair and equitable agreement?
It is a negotiated solution between holder and heirs when strict law is not sufficient or does not apply, in accordance with the spirit of the 1998 Washington Principles.
Has the portrait of Amalie Zuckerkandl been returned?
No. After examining its complex provenance and competing requests, the Austrian Restitution Council recommended its maintenance at the Belvedere.
Where to start to check a provenance?
It is necessary to consult museum databases and reports, inventories, sales archives and restitution files, then distinguish each transfer instead of assuming that a trajectory applies to all works.
