The omission enraged the Israeli and German Jewish officials invited to the Sept. 27 ceremony.
Among those who stated their intention to boycott the ceremony were Israeli Ambassador Avi Primor; Ignatz Bubis, chairman of the Central Council of Jews in Germany; and Yoram Oberkovitz, a member of the Israeli Olympic Committee.
The German Olympic Committee changed the plaque's text after intensive negotiations with the Jewish officials.
Committee members said they would not be able to change the text in time for the ceremony, but they pledged to do so as soon as possible.
Palestinian terrorists belonging to the Black September movement infiltrated the Olympic village on Sept. 5, 1972, the 11th day of the Munich Olympics.
The terrorists killed two Israeli athletes and took nine others hostage, demanding the release of 200 Arab prisoners in Israel.
In a shootout at the airport later that day when German police attempted to free the hostages, all nine hostages were killed, as were a German policeman and five of the terrorists. Three of the Palestinians were arrested.
The games were halted for 24 hours.
Relatives of the Israeli victims blamed the German police for botching the airport rescue attempt and sued the local authorities for compensation.
The trial is still pending.
