Art detectives investigate fraud in cases of art forgery and crime

Art and cultural artifacts are not only expressions of human creativity and history, but also a recurring lucrative target for criminals. The art world is regularly the scene of complex crimes such as looting, smuggling, and forgery.

Each of these offenses brings its own challenges and causes significant damage, especially to honest buyers and collectors.

Looted art , often acquired during wartime or through theft, must be painstakingly traced and correctly attributed through detective work and provenance research.

Art smuggling, in turn, causes valuable cultural artifacts to disappear onto black markets, depriving them of their provenance and legal display. Art forgeries : they deceive buyers and experts alike and can be an extremely lucrative business for forgers. At the same time, they mean immense financial losses for honest collectors and institutional buyers.

Experts estimate that one in three works of art is a forgery

Experts estimate that one in three works of art could be a forgery, making the art forgery trade extremely lucrative. However, this poses a significant financial risk for honest buyers and collectors, as they pay large sums for supposedly original works.

art detectives, provenance researchers , and art commissioners come into play – experts dedicated to solving these crimes. With their specialized expertise and sophisticated methodology, they can shed light on the darkest corners of the art market.

Their work often begins with careful research and the application of state-of-the-art technologies to verify the authenticity of works of art.

The task of exposing art forgeries is, for example, undertaken by specialized art detectives at the State Criminal Police Office (LKA) .

These experts use specialized laboratories to verify the authenticity of artworks. With state-of-the-art technologies and scientific methods such as forensic analysis , radiological examinations , and chemical material testing, they scrutinize the works down to the smallest detail. They also work closely with art historians and conservators to uncover historical and stylistic inconsistencies.

Through their meticulous detective work, they contribute to keeping the art market clean and maintaining trust in the art trade. Every fraud uncovered and every forgery exposed protects honest buyers from financial losses and contributes to the transparency and integrity of the art market. The work of art detectives is therefore an essential component in the fight against art crime.

Art crimes – Spectacular cases that caused a sensation

Among the numerous art crimes that came to light during the 20th and early 21st centuries, a few exceptional cases have garnered particular attention due to their execution or cultural significance. The following selected criminal acts fall into this category.

The master forger Wolfgang Beltracchi 

Wolfgang Beltracchi managed to deceive the art world and thereby amass a fortune. The scandal surrounding Germany's biggest art forger after the Second World War is known far beyond its borders.

But, as so often happens in such cases, the “Beltracchi system” also began to show cracks. In the spectacular case of Wolfgang Beltracchi, it was ultimately unexpected color details that exposed his deceptions and unmasked him.

However, it remains unclear to this day how many forged works Beltracchi actually produced. He himself claims to have sold approximately 300 forgeries, of which around 100 have been exposed as such so far.

This art scandal continues to cause a stir and raises questions about integrity and verification mechanisms in the art world.

Hitler's bronze stallions

In the fall of 2013, a Berlin art dealer received an offer that left her speechless: Two oversized bronze sculptures by the Nazi sculptor Josef Thorak were to be sold for 3.1 million euros. These imposing horse statues had once stood in front of Hitler's Reich Chancellery in Berlin and had been considered lost since the end of the Second World War.

The art dealer, skeptical and alarmed by the works' dubious provenance, immediately contacted art commissioner René Allonge . Allonge, who had been searching for the missing sculptures for years, immediately recognized the significance of this lead.

He and his team began their investigation of the two oversized bronze sculptures by Nazi sculptor Josef Thorak immediately after receiving a tip from a Berlin art dealer. Through forensic analysis, historical research, and comparisons with contemporary photographs and archival documents, Allonge was able to confirm the sculptures' authenticity.

The investigations revealed that the horses were indeed the ones that had once stood in front of Hitler's Reich Chancellery in Berlin and had been considered lost since the end of the war. After thorough examination, it emerged that the sculptures had gone missing in the chaos of the post-war period and had likely ended up in the hands of private collectors, without ever having appeared in official museums or public collections.

In addition, the investigation yielded valuable clues about other missing artworks and their possible current locations. The findings led to the initiation of further investigations, which are now also dedicated to the whereabouts of missing artworks from the Nazi era.

The biggest art theft in East Germany

In December 1979, the largest art theft in the history of East Germany took place: Several valuable paintings were stolen from Friedenstein Castle in Gotha. Despite intensive investigations, the masterpieces remained missing for almost four decades, and the perpetrators and the whereabouts of the paintings remained a mystery for a long time.

It was the night of December 14, 1979, during a violent storm and rain, when two men approached Friedenstein Castle. They climbed the western facade, near the west tower, and reached the level of the second floor, just below the roof, using a rain gutter and the lightning rod. There, they opened an unsecured window, entered, and stole five paintings from three exhibition rooms.

On their way back to the floor, one of the paintings fell and the frame broke. Nevertheless, the thieves continued their escape with their valuable loot. Irene Geismeier, the director of the Berlin Gemäldegalerie, estimated the value of the stolen paintings at 4.5 million DM on the art market at the time. It was the most spectacular art heist in the history of East Germany.

The paintings seemed to be lost forever. Gerd Schlegel , then working for the Gotha Criminal Police and a member of a special commission investigating the robbery, was also convinced that the paintings were gone for good. He described the burglary at Friedenstein Castle as the most significant event of his career.

It wasn't until 2018 that an unexpected phone call to Gotha's mayor brought new hope to the stalled case. An anonymous caller provided crucial information about the whereabouts of the stolen artworks. This information not only led to a renewed investigation but also rekindled hope of recovering the missing masterpieces.

A Hamburg journalist announced a sensation shortly afterwards, which was published by “SPIEGEL online” and spread rapidly: All five stolen pictures had resurfaced in 2019 and were successfully verified for authenticity shortly afterwards.

Dresden jewel theft at the Green Vault

In November 2019, a spectacular jewel theft shook the art world: 21 pieces of jewelry with diamonds and jewels worth over 116.8 million euros were stolen from the Green Vault in Dresden, one of the best-secured museums in Germany.

The precise execution of the break-in raised urgent questions: Were the thieves perfectly prepared, or did they reveal serious security gaps in the museum?

In an NDR Kultur episode of "Art Crime – True Crime Meets Culture," the Green Vault case was revisited in 2023. The team visited the crime scene in Dresden and reconstructed the sequence of events. Local expert and MDR reporter Ina Klempnow provided insights into the meticulously planned burglary and the authorities' reactions.

The investigation was supported by renowned art detective and private investigator Artur Brand , who has already tracked down numerous stolen works of art.

Through interviews and on-site observations, the team of journalists examined potential security flaws and the precise sequence of events during the break-in. Together with Brand, they also analyzed the perpetrators' motives and methods.

In May 2023, five young men from the notorious Berlin Remmo clan were convicted. During their trial at the Dresden Regional Court, a large portion of the stolen loot was returned as part of a plea deal at the end of 2022.

Almost 12 months after the conclusion of the first criminal trial in connection with the jewel theft from the Green Vault, a legal battle over claims for damages is now underway. A civil chamber of the Dresden Regional Court is now dealing with the lawsuit filed by the Free State of Saxony against the security firm of the Dresden State Art Collections (SKD) .

The Free State accuses the security company of misconduct by four security guards during the spectacular break-in at the historically reconstructed part of Saxony's Treasury Museum, as reported by the Mitteldeutsche Zeitung at the end of April 2024.

The Theft of the Mona Lisa

The theft of the Mona Lisa from the Louvre in 1911 is considered one of the most significant art thefts in history. On the morning of August 21, 1911, a museum employee noticed that Leonardo da Vinci's famous painting was no longer in its place. The world was shocked, and the French police launched an intensive, two-year investigation, which initially proved unsuccessful.

The perpetrator, Vincenzo Peruggia , an Italian craftsman who had worked at the Louvre for a time, kept the painting hidden in his Paris apartment. Peruggia believed the masterpiece belonged in Italy, as he thought it had been stolen during the Napoleonic Wars. In 1913, he attempted to sell the Mona Lisa to an art dealer in Florence. However, the dealer alerted the authorities, leading to Peruggia's arrest and the painting's safe return to Paris.

Thanks to the theft, the Mona Lisa gained enormous worldwide fame and became a symbol of immeasurable cultural value. This case demonstrates how a spectacular theft can significantly influence not only the art world but also the public perception of a work of art.

Booming art market and Helge Achenbach's fraud scheme

The art market experienced an unprecedented boom in the 2000s, and one of the most prominent figures during this golden age was Helge Achenbach . As Germany's best-known art consultant, Achenbach enjoyed excellent connections to renowned artists such as Gerhard Richter and Jeff Koons, as well as to influential collectors and business leaders. His reputation and networks enabled him to rise rapidly in the art world.

But behind the glittering facade lay an elaborate fraud scheme. Achenbach exploited his position and the trust of his wealthy clients to make substantial profits. He bought up works of art, inflated their prices, and then resold them at drastic markups – without his clients' knowledge.

Particularly prominent victims, such as the Aldi heir Berthold Albrecht, paid millions for works whose values ​​Achenbach had manipulated.

In 2014, the web of lies collapsed when Achenbach was arrested and ultimately sentenced to several years in prison. The sensational case shook the art world and exposed the fragile mechanisms and vulnerability of the booming market to fraud. Achenbach's story remains a stark reminder of how easily trust and illusions can be abused in the glamorous world of art.
