The investigation of the Institute of Pacific Relations (IPR) was the first major investigation initiated by the subcommittee. Some people accused the IPR leadership of spying for the USSR. Owen Lattimore, editor of the IPR journal "Pacific Affairs", was especially singled out for criticism. It is also believed that the pressure of the investigation triggered the suicide of the UN Assistant Secretary General Abraham Feller on November 13, 1952.
