Scientific and Cultural Conference for World Peace

It was arranged by a Communist Party USA front organization known as the National Council of the Arts, Sciences, and Professions. The conference was a follow-up to a similar gathering, the strongly anti-America, pro-Soviet World Congress of Intellectuals which was held in Poland, August 25 - 28, 1948.
