Jill Murphy

Jill Murphy, the controversial chief of staff for J. Paul Getty Trust Chief Executive Barry Munitz, disclosed Thursday that she will leave her post by the end of the year. Murphy, 33, announced the departure to her staff in the afternoon after describing her plans in an e-mail to The Times. In the e-mail, she summarized a letter written in November to Munitz, saying that they had agreed on a plan for her exit. Murphy's designation as chief of staff is an unusual one in the nonprofit world.
