Under current director Neal Benezra, who was recruited from the Art Institute of Chicago in 2002, SFMOMA achieved an increase in both visitor numbers and membership while continuing to build its collection. In 2005 the museum announced the promised gift of nearly 800 photographs to the Prentice and Paul Sack Photographic Trust at SFMOMA from the Sacks' private collection. The museum saw record attendance in 2008 with the exhibition "Frida Kahlo", which drew more than 400,000 visitors during its three-month run.
