The Hirshhorn Museum and Sculpture Garden has received a $2 million gift from trustee Joleen Julis and her husband, Mitch, museum officials announced. The donation is the largest gift from an individual ever made to the Smithsonian’s modern and contemporary art museum.

The donation will establish the “Future Fund,” a $4 million effort to re-design the museum’s lobby and sculpture garden, according to Hirshhorn Director Melissa Chiu.
