Georgetown Dean to Lead Philanthropic MacArthur Foundation

"The opportunity for what our money can do is particularly important now," said Robert E. Denham, chairman of the foundation's board of directors, and a lawyer at Munger, Tolles & Olson in Los Angeles. "It magnifies the importance of making smart choices."

Gallucci will replace Jonathan Fanton, retiring after two terms as president. Denham said the board was sold on Gallucci based on his extensive international experience and his ability to make difficult decisions under duress.
