Summary

Sotheby’s announced a landmark New York auction of a single‑owner collection that unites French 20th‑century design with modern masterpieces. The assemblage, built by Terry and Jean Ginsbourg, showcases over a hundred pieces ranging from iconic French furniture to works by Agnes Martin, Mark Rothko, Pablo Picasso and Alexander Calder, creating a rare cross‑disciplinary narrative. The collection’s strength lies in its curatorial rigor, guided by Parisian design legends Jacques Grange and Pierre Pasbon. They emphasize the French tradition of line, balance and material experimentation, evident in the intimate, never‑commercialized pieces by Alexandre Noll and the meticulous craftsmanship of mid‑century chairs and tables. Highlights include Claude Lalangue’s fifteen‑mirror installation originally commissioned for YSL, and a monumental Rothko‑scale canvas praised for its unprecedented format and chromatic depth. The auction also features a striking rug by Rulman, described as the most beautiful ever seen, underscoring the collection’s blend of visual art and decorative mastery. The sale, set for April 22, signals robust investor appetite for high‑end design objects and reinforces the market’s willingness to price integrated art‑design narratives at premium levels, potentially reshaping benchmarks for future design auctions.

Original Description

There are collections that document taste, and there are collections that reveal a way of seeing. Shaped by instinct rather than strategy, and arranged by legendary Parisian decorator Jacques Grange, it brought together Rothko and Royère, Agnes Martin and Alexandre Noll, Claude Lalanne and Jean-Michel Frank under one roof in a home Terry and Jean describe as "New York on the outside, Paris on the inside." The result is something that defies easy categorization: a living environment in which 20th century French design and masterworks of contemporary art speak to each other with startling clarity.

Among the highlights: a monumental Rothko on paper of a scale and color balance almost never seen at auction, fifteen Claude Lalanne mirrors commissioned directly by Yves Saint Laurent and Pierre Bergé, and a Ruhlmann rug that left the sale's own specialists at a loss for words. This is the story of how two people, guided by curiosity and an almost scientific precision of eye, assembled one of the great private collections of our time.

In April and May 2026, Sotheby’s will present a landmark selection from the Collection of Jean & Terry de Gunzburg. The sale series is led by Collection of Jean & Terry de Gunzburg – Design Masters, a dedicated single-owner auction on 22 April 2026. Bringing together approximately 125 works, the sale marks a once-in-a-generation moment for the design market: the most valuable single-owner design sale in Sotheby’s history and the first standalone single-owner design auction to be staged at Sotheby’s new home in the historic Breuer building in New York.
