During the Gilded Age in New York City, Mrs. Astor’s ballroom was the place where the aristocracy of Gotham could be counted and codified. Last night, at a glittering gala held at the Whitney Museum, the elite of the international design world assembled for their own roll call. Hosted by Architectural Digest editor in chief Margaret Russell, the occasion was a celebration of the AD100, AD’s definitive lineup of the most influential architects and interior designers working today. It was one enchanted evening that saw the old guard mixing with the new, the great standard bearers of design standing side by side with the iconoclasts, and tastemakers of every stripe reveling in the heady atmosphere.

If one wanted to trace a family tree of design genealogy, this was the place for it. “I’m still astonished when I think that I’m on the same list—any list!—as Robert A.M. Stern,” said architect Brian Sawyer, referring to his mentor, former employer, and fellow AD100 honoree. In fact, Stern’s office represents one of the strongest limbs of the design family tree, boasting a stellar alumni group that includes AD100 talents Daniel Romualdez, William T. Georgis, John Berson, John Ike, Thomas Kligerman, and Joel Barkley, all of whom were present for the festivities.

Madeline Stuart perhaps best summed up the collegial vibe in the room: “I’m surrounded by people whose work has inspired and delighted me for years. Some of my idols are standing just a few feet away. Seeing all these extraordinary talents gathered in one place is a bit overwhelming, especially when I remind myself that I’m one of them!”
