NEW YORK—Last Monday, celeb couple Richard Gere and Carey Lowell co-chaired the fourteenth edition of Artwalk NY, bringing together art-world mainstays and high society to raise money for the Coalition for the Homeless and pay tribute to the late Robert Rauschenberg. The event featured a cocktail reception along with a silent and live auction, which included works by such big-name artists as Chuck Close, Jeff Koons, Yoko Ono, Zhang Huan, and of course, Rauschenberg, whose Soviet American Array VII (1988–91) brought in the highest bid — $50,000. Alec Baldwin was in attendance, as well as photographer William Coupon, artist Daryl Pottorf, and Performa director RoseLee Goldberg.

On Friday, the Dia Art Foundation's annual fall gala took place. This year's festivities focused on the arrival of Philippe Vergne as Dia's new director as well as artist Zoe Leonard's project Deroterro, which will inaugurate a yearlong program of Dia in New York City at the Hispanic Society. To toast the recent changes taking place at the foundation, Dia chairman Nathalie de Gunzberg and her husband Charles were joined by a range of design and art-world figures, including fashion icon Kate Spade, Museum of Modern Art associate director Kathy Halbreich, and artists Lawrence Weiner and Kara Walker.
