Researchers Identify Enslaved Boy in Joshua Reynolds Painting

Researchers in the U.K. have identified the enslaved boy depicted in Joshua Reynolds's 1748 painting of Royal Navy lieutenant Paul Henry Ourry. For centuries known only as "Jersey," the boy has been identified as George Walker, also called Boston Jersey, through baptismal and admiralty records. Walker was baptized at age 15 in Westminster in 1752, served on HMS Monmouth and HMS Deptford, and was discharged in 1753, after which his fate remains unknown. The research, a collaboration between the National Trust, the National Gallery in London, and Royal Museums Greenwich, also used scientific analysis to reveal Reynolds's original compositional intentions.

An anonymous whistleblower has filed a complaint alleging misconduct by leadership at the Palm Springs Art Museum, including improper movement of funds between accounts to address cash shortages, the forced resignation of a former director based on fabricated staff complaints, and a failure to properly interview external candidates for the director position.

"Kultursenator ist kein Nebenjob"

Berlin's finance senator Stefan Evers is set to additionally take on the role of culture senator following the resignation of Sarah Wedl-Wilson, a move criticized as a stopgap solution that creates a conflict of interest between austerity and cultural advocacy. Meanwhile, the Venice Biennale faces multiple controversies: critics question how to evaluate curator Koyo Kouoh's posthumous main exhibition "In Minor Keys," completed after her death in May 2025; Israeli artist Belu-Simion Fainaru speaks out against his exclusion from the Biennale competition, calling it politically biased and reminiscent of historical persecution; and German press decries the politicization of the Biennale, particularly the exclusion of Israel and Russia from the competition.

Venice Biennale 2026: How Do You Critique a Posthumous Exhibition?

The article, published by ArtReview, examines the upcoming 61st Venice Biennale (2026), titled *In Minor Keys*, which was conceived by artistic director Koyo Kouoh before her death from cancer in May 2025 at age 57. The exhibition, based on Kouoh's drafted concept and completed by a curatorial team including Rory Tsapayi, Siddhartha Mitter, Marie Hélène Pereira, Gabe Beckhurst Feijoo, and Rasha Salti, adopts a musical metaphor of "minor-ness" and aims to avoid the pitfalls of previous Biennales by focusing on soul frequencies and dissonant harmony rather than direct commentary on world crises. The author, Martin Herbert, questions how critics will respond to a posthumous exhibition of this unprecedented scale, noting that previous artistic directors like Robert Storr, Cecilia Alemani, Christine Macel, and Adriano Pedrosa have faced varied critical receptions.

Daniel Sikkema, the estranged husband of murdered New York art dealer Brent Sikkema, was found guilty in Manhattan federal court on charges related to a murder-for-hire plot.

Russia's 2026 Venice Biennale Will Not Open to the Public, and Other News.

Russia's pavilion at the 2026 Venice Biennale will be closed to the public for nearly the entire run of the exhibition (May 9–November 22), with access limited to a brief preview period for press and invited guests. Instead of physical access, visitors will experience the pavilion's project—titled 'The Tree Is Rooted in the Sky'—via video documentation displayed on exterior screens. The arrangement is widely seen as a compromise shaped by international sanctions and political backlash over Russia's return following its absence after the 2022 invasion of Ukraine. In other news, Matthieu Blazy unveiled his first Chanel cruise collection in Biarritz; San Francisco appointed Matthew Goudeau as its first-ever executive director of arts and culture; the Saudi Arabia Museum of Contemporary Art received a $490 million construction grant from Diriyah Company; and online auction sales grew 8 percent in 2025, generating $423.9 million.

New York art world spared worst of logistics woes

New York's spring art fairs—including Frieze, Tefaf, Independent, and Nada—are proceeding largely on schedule despite ongoing disruptions from the war in Iran. Airspace closures, reduced flights, rising fuel costs, and the closure of the Strait of Hormuz have strained global art logistics, forcing rerouting, last-minute cancellations, and cost increases of up to 2,500%. Logistics firms like Hasenkamp and Gander & White report that while shipments are still arriving, the system has become fragile, with clients prioritizing safety and resilience over speed.

Is the US about to be humiliated on the world’s most prestigious cultural stage?

More than 70 prominent international artists have signed an open letter demanding the exclusion of the United States, Israel, and Russia from the 2026 Venice Biennale, accusing those governments of committing war crimes and atrocities. The controversy centers on the US pavilion, which will feature Mexico-based American artist Alma Allen, whose abstract, anodyne sculptures were chosen by a last-minute commissioner with no art-world experience—a luxury pet food store owner from Florida who reportedly gained the role through connections at Mar-a-Lago. The Biennale's five-person jury has already resigned amid the furor, and Russia is returning to the event for the first time since its 2022 invasion of Ukraine.

Brent Sikkema’s Husband Convicted
