ARTS & MEDIA: The Sosnoffs have a strong interest in the arts and are avid collectors. Among the museums they have supported are the Guggenheim Museum; the Art Institute of Chicago; the Museum of Fine Arts, Houston; and the Aldrich Contemporary Art Museum in Ridgefield, Connecticut. Past grantees in the performing arts include the American Ballet Theater, which received $5 million from the couple; the Palm Beach Opera; Lincoln Center for the Performing Arts; the Manhattan Theatre Club, the Roundabout Theatre Company; the Signature Theatre and New York City’s Metropolitan Opera.

ANIMALS: The Sosnoffs maintain an active interest in animals; Martin competes in dressage, and Toni has bred standard and toy poodles for over 25 years.
