Lovers to friends: the intimate story of Van Gogh's sister-in-law and the artist Isaac Israëls

The Van Gogh Museum in Amsterdam has published 103 letters from Dutch Impressionist painter Isaac Israëls to Jo Bonger, Vincent van Gogh's sister-in-law, revealing a previously secret romantic relationship between them. The museum is also presenting an exhibition titled "Captivated by Vincent: The Intimate Friendship of Jo van Gogh-Bonger and Isaac Israëls" (through January 25, 2026), which explores their brief physical relationship in the 1890s and its aftermath, including how Israëls incorporated Van Gogh's paintings into his own portraits—a practice he called "Vincenting." Twelve of these portraits are on display for the first time.
