A Catholic nun from Pennsylvania is the first non-Jew and non-Israeli to receive Yad Vashem's Award for Excellence in Holocaust Education. Sister Gemma del Duca, a Sister of Charity and former chair of the history department at Seton Hill University in Greensburg, Pa., has been leading seminars for Holocaust education with the Yad Vashem Holocaust Memorial for two decades. The seminars, started on her initiative, are intended for groups of Catholic educators and clergy, primarily from the United States. According to Yad Vashem, hundreds of educators have taken part in the seminars. -- Catholic News Service
