The Museum of Modern Art announced Thursday that Los Angeles-based philanthropist David Geffen has given a $100 million gift toward the Museum’s renovation and expansion, the largest gift to the institution’s Campaign.

In recognition of Mr. Geffen’s extraordinary gift, three floors of new galleries, created as part of the Museum’s expansion into the tower being constructed immediately to the west of the Museum at 53 West 53rd Street, will be named The David Geffen Wing. In addition, the fourth-floor suite of galleries in the current museum building will be named The David Geffen Galleries this spring.

The building project will add 50,000 square feet of gallery space, allowing the Museum to reconceive the presentation of its collection and exhibitions, and will provide greater visitor accessibility through the enhancement of the Museum’s public areas.
