Director of Barnes Foundation Steps Down The Barnes Foundation announced on Tuesday that Derek Gillman will step down as executive director and president as of Jan. 1 to become a visiting professor at Drexel University's Westphal College of Media Arts & Design. Mr. Gillman, who joined the Barnes in 2006, led the move of the Barnes Collection and its world-class art to its new home, designed by Tod Williams Billie Tsien Architects, in central Philadelphia. During his seven-year tenure, he oversaw the fund-raising campaign for the Barnes's new $150 million building and the addition of $50 million to its endowment. Since the Barnes opened in its new space last year, annual attendance has grown to more than 325,000 from 60,000. A search is underway for Mr. Gillman's replacement. In the meantime, Margaret Zminda, the foundation's executive vice president, chief financial officer and chief operating officer, will serve as acting director. "I have achieved all I had hoped to for the Barnes - and more," Mr. Gillman said in a statement. The Barnes is really well positioned for the future and I am excited about going back into higher education. At Drexel, Mr. Gillman will contribute to the department of art and art history and the graduate program in museum leadership.
