The Holocaust Educational Foundation, a 35-year-old organization that has recorded the testimony of survivors of the Holocaust and has helped create courses in the Holocaust at hundreds of colleges, is becoming part of Northwestern University. According to a news release issued today, the university and the foundation have long collaborated in staging an interdisciplinary conference and a summer institute. The foundation, which in 2000 financed an endowed chair in Holocaust studies at Northwestern, recently donated $1-million to the university and plans a $5-million gift to endow the program permanently.
