Who Is Peter Brant Jr.?
Peter Mark Brant Jr. was born on December 30, 1993, and raised in Greenwich, Connecticut. He is also identified in some coverage as Peter Brant II. His father, Peter M. Brant, is a prominent businessman, publisher, and art collector. His mother, Stephanie Seymour, is one of the most recognized American supermodels of the late 1980s and 1990s. Seymour and Peter M. Brant married in 1995.
Peter Jr. did not build his public profile through a single conventional career path. Instead, he became known through the Brant family’s combined presence in fashion, art collecting, and society, appearing at events and taking on creative projects that reflected those family interests. His most substantive public work came through collaboration with his brother Harry.
The MAC Cosmetics Collection with Harry Brant
In 2015, Peter and Harry Brant partnered with MAC Cosmetics to launch a makeup and skincare collection. The project received genuine press attention, including coverage in W Magazine and artnet News, and was positioned as gender-neutral and inclusive across gender identities and expressions. The brothers were jointly the creative force behind it, and the collection was widely referred to in coverage as the Brant Brothers MAC collaboration.
The project was notable for its timing. Gender-inclusive beauty products were still a relatively new conversation in mainstream cosmetics marketing in 2015, and the Brant brothers’ involvement gave the launch a foothold in both fashion media and the art world press. The collaboration was not an independent brand launch; it was a co-created collection developed within MAC’s existing structure.
Interviews published around the launch gave readers a clearer picture of both brothers as engaged, opinionated collaborators rather than passive celebrity attachments to the project. Peter and Harry spoke together in coverage and were presented as equals in the creative direction of the collection.
Art World Involvement
Beyond the MAC project, Peter Brant Jr. has also been involved in the art world in a more direct capacity. He is credited as a co-curator of an exhibition featuring artist Elizabeth Peyton, presented through Dylan Brant Fine Art. The exhibition, titled Countess Olenska, placed him in a curatorial role within a family-connected art enterprise.
This involvement is consistent with the broader context of the Brant family’s place in contemporary art. Peter M. Brant is one of America’s significant private art collectors, and the family’s engagement with artists, galleries, and exhibitions has been a constant presence across decades. Peter Jr.’s co-curation reflects that environment, even if his independent curatorial output beyond this project is not extensively documented in public sources.
For readers interested in the intersection of collecting families and the contemporary art world, coverage from outlets like First Business Mag offers useful context on how family legacies shape involvement in creative industries.
The Brant and Seymour Family
Peter Jr. is one of three children born to Stephanie Seymour and Peter M. Brant. His brother, Harry Brant, died in January 2021 at the age of 24 following an accidental drug overdose. The brothers had been closely linked publicly throughout their adult lives, and Harry’s death was widely reported across fashion and society media. Peter Jr. and Harry were frequently photographed together and were seen as a unit in their shared creative projects.
Their sister, Lily Margaret Brant, is also a child of Seymour and Peter M. Brant, completing the trio of children from their marriage.
Peter Jr. also has a maternal half-brother, Dylan Thomas Andrews, who is Stephanie Seymour’s son from an earlier relationship. Dylan is Peter Jr.’s half-sibling through their shared mother rather than a full sibling.
The family’s social and professional world has always been unusually unified. Seymour’s modeling career, Peter M. Brant’s art collecting and publishing interests, and the children’s own appearances in fashion and art spaces have kept the Brant name consistently present across those industries for decades.
A Public Profile Shaped by Family and Collaboration
Peter Brant Jr. is not a figure whose public record reads like a conventional professional biography. He has not pursued a single defined career with a clear trajectory, and coverage of him tends to appear in the context of family events, the MAC collaboration, or art-world activities tied to the Brant name.
What is documented is genuine: a cosmetics collaboration that received real press attention and approached beauty from a thoughtful, inclusive angle; a co-curatorial credit within a serious art exhibition context; and a consistent presence in a family that has shaped American art collecting and fashion culture for a long time. His partnership with Harry, in particular, gave him a public identity that was recognized in its own right, not simply as an extension of his parents’ fame.
Since Harry’s death, Peter Jr. has maintained a lower public profile, though his connection to the Brant family’s art and fashion activities continues.
