In recent weeks, generous audiences at Berkeley Repertory Theatre have donated $7,835 to help people in the wake of the devastating earthquake in Haiti. The funds - which were collected by volunteer ushers following performances of Athol Fugard's Coming Home - have been given to Doctors Without Borders, the international nonprofit organization that was honored with the Nobel Peace Prize for its ongoing efforts to provide aid in nearly 60 nations to people whose survival is threatened by violence, neglect, or catastrophe.
