Three Harvard professors attended a conference of scholars and intellectuals Sunday which discussed the politicization of the United Nations Education, Scientific and Cultural Organization (UNESCO) and its recent actions against Israel.

David S. Landes, Goelet Professor of French History, Daniel P. Moynihan, professor of Government, and Orlando H.L. Patterson, professor of Sociology, were all members of the conference committee which discussed the ramifications of the 1974 UNESCO resolution charging Israel with jeopardizing Moslem monuments during archeological excavations in Jerusalem.

This resolution prohibited Israel from participating in their own regional group of UNESCO, and since all of UNESCO's business is done in regional groups, this in effect barred Israel from involvement in UNESCO, Landes said yesterday.

Landes said he and many of the other delegates will boycott UNESCO functions as a matter of conscience "until the politicization of a supposedly neutral organization is halted."
