His story is not one of red carpets and paparazzi, but of deliberate discretion. This Bernard Lagrange biography gathers everything publicly known about Phoebe Tonkin’s husband, from his art history studies at Princeton to the elegant New York wedding that united the couple on May 10, 2025.

Who Is Bernard Lagrange?
Bernard Lagrange is an art dealer and art advisor who rose to public attention as the husband of Australian actress Phoebe Tonkin. While his wife built her fame through television roles as Hayley Marshall in The Vampire Diaries and The Originals, Lagrange made his name in a completely different arena: the international art market, described in coverage as an art dealer for Sotheby’s, one of the world’s foremost auction houses.
What makes Lagrange stand out in the celebrity-spouse landscape is his commitment to privacy. He maintains a private Instagram account with a self-deprecating bio that reads, “Worst salesman in the history of art.” Even after marrying a television star, he has granted no interviews and made no public statements, a man who chose to stay out of the spotlight and largely succeeded.
Age, Birth Date and Early Life
Details about Bernard Lagrange’s age, birth date, and early life have not been publicly disclosed, and this appears to be by design. Unlike his wife, whose Australian upbringing has been widely documented, Lagrange entered the public record only when his relationship with Tonkin became news in late 2024. His exact date of birth, birthplace, and family background remain unreported by any reliable outlet.
One unverified claim describes him as the son of a hedge fund figure, but this has not been confirmed by credible sources. What can be said with confidence is that he studied art history at Princeton University, one of America’s most prestigious Ivy League institutions. Beyond that foundation, the chapters of his early life remain, for now, closed to the public.
Education: Art History at Princeton
According to reports based on his professional profile, Bernard Lagrange pursued art history at Princeton University, laying the groundwork for a career in the art world. Princeton’s art history program is among the most respected in the world, and that training shaped his professional direction: dealing in and advising on fine art at the highest commercial level.
His education explains both his career and his discretion. The art world, particularly the auction-house tier where Lagrange operates, is famously relationship-driven, valuing discretion and trust over visibility. Rather than chasing public recognition, Lagrange built his reputation through expertise and connections.
Career at Sotheby’s
Bernard Lagrange has spent the better part of his professional life at Sotheby’s, the world-renowned auction house headquartered in New York. Outlets citing his professional background report that he holds the role of Special Assistant to the CEO, Contemporary Art & Digital, with a tenure spanning roughly a decade. These details come from secondary reporting attributed to his LinkedIn profile, so they are best understood as reported rather than officially confirmed.
Before his long run at Sotheby’s, he reportedly gained early experience through internships at Frieze and the Gagosian Gallery, two heavyweight names in the contemporary art ecosystem. One Australian outlet additionally reported that he serves as a member of the conservation committee at the Whitney Museum of American Art in New York City, a role that would place him among the patrons who help guide one of America’s leading modern art museums.
Instagram and His Private Nature
Bernard Lagrange’s Instagram handle is reportedly @berndogl, and fittingly, the account is private. Even as his wife shares carefully curated glimpses of their life together with millions of followers, he keeps his own digital presence locked to friends and acquaintances. Fans who go searching for his personal posts will find a closed door rather than an open book.
Before their engagement, the couple kept their romance almost entirely out of the public eye, with the exception of a handful of Instagram posts from Tonkin. When they did go public, they did so in their own aesthetic: grainy, film-style photography shot by their friend Mark Bauch, with no press release and no magazine exclusive. It was intimacy staged as art, not as celebrity content.
Relationship with Phoebe Tonkin
The precise timeline of Bernard Lagrange and Phoebe Tonkin’s relationship remains private. What is known is that the couple had been together quietly for some time before October 2024, when Tonkin confirmed the romance by revealing their engagement. Before Lagrange, Tonkin was most famously in a long-term relationship with her Vampire Diaries co-star Paul Wesley from 2013 to 2017, and was later linked to musician Alex Greenwald in 2020.
Friends of the couple have described the pairing as a natural fit: the actress who had grown weary of Hollywood spectacle finding a partner whose world values quiet connoisseurship over noise. The couple’s inner circle, including friends like Teresa Palmer and Claire Holt, celebrated the engagement enthusiastically, suggesting a relationship that had been an open secret among those who mattered most.
The Engagement in Provence
During an interview with Vogue, Phoebe Tonkin confirmed the romantic details of the proposal: “We got engaged in Provence, in a house by ourselves, just the two of us.” The South of France setting was a fittingly cinematic choice, and the intimacy of the moment, just the two of them, alone in a house, was perfectly on brand for their low-key love story.
The official announcement came on Instagram on October 29, 2024, when Tonkin shared the “summer of love” carousel. The opening image, a striking black-and-white photograph, captured the couple kissing while her elongated oval-cut diamond solitaire caught the light. Friends including Rosie Huntington-Whiteley and Alycia Debnam-Carey flooded the comments with congratulations, and the post quickly became one of the most talked-about celebrity engagements of the year.
The Wedding: A Chic New York Celebration
Bernard Lagrange and Phoebe Tonkin married on Saturday, May 10, 2025, in a wedding that blended high fashion with understated elegance. The ceremony took place at All Souls Church in uptown Manhattan, a spiritual, non-denominational service focused on the couple’s personal connection rather than strict tradition. The bride wore a custom ivory lace gown by Chanel, while Bernard opted for a classic black suit.
The rehearsal dinner was held at the iconic Mr. Chow, where Tonkin wore a vintage John Galliano newspaper-print gown. The main reception took place at Eleven Madison Park, one of New York City’s most prestigious restaurants, where she changed into a sleek gown by Magda Butrym. The guest list read like a who’s who of Australian expatriate glamour: Claire Holt served as one of the bridesmaids, while Margot Robbie, Teresa Palmer, Samara Weaving, Nina Dobrev, Annabelle Wallis, Eiza González, Bella Heathcote, and Lara Worthington were all in attendance.
Net Worth and Lifestyle
Bernard Lagrange’s net worth has not been publicly disclosed, and any specific figures found online should be viewed with skepticism, since his finances have never been reported by reliable sources. That said, the contours of his lifestyle are visible: a Princeton education, a decade-long career at Sotheby’s, involvement with the Whitney Museum, and a New York wedding at venues like All Souls Church and Eleven Madison Park all point to a comfortable life within Manhattan’s art and culture circles.
Since the wedding, the couple has remained based in New York, where both maintain their careers, hers in film and television, his in the art market. They remain one of the more intriguing pairings in contemporary celebrity culture: a television star and an art world professional who share a taste for privacy and keeping the most important parts of their life just for themselves.
Conclusion
Bernard Lagrange may have become famous as Phoebe Tonkin’s husband, but his biography reads as the portrait of a man who built a substantial life long before the spotlight found him. An Ivy League art history education, a decade at one of the world’s great auction houses, and an instinctive aversion to publicity define him far more than his marriage certificate does.
From the quiet proposal in Provence to the Chanel-clad ceremony at All Souls Church, Lagrange and Tonkin have written their love story on their own terms. Whatever the future holds, one thing seems certain: Bernard Lagrange will continue to be known on his own conditions, a private man in a public marriage.
