Angus Cameron, 93, the former editor-in-chief of a top publishing house who was forced to resign during the McCarthy era because of his leftist sentiments, died Nov. 18 in Charlottesville, Va.

Mr. Cameron joined Little, Brown in 1938 and quickly rose to power, gaining a reputation for his keen attention to the public's sensibilities, as well as an appreciation for the creativity of his authors.

In 1951, the company asked the leftist sympathizer to clear his schedule with them after anti-Communist conservatives attacked him for his involvement with several groups. Mr. Cameron refused and left the company, after which he formed a publishing house with partner Albert Kahn. In 1955, the pair published False Witness by Harvey Matusow, who confessed to falsely accusing 200 people of being Communist sympathizers during the height of McCarthyism.

Mr. Cameron testified before the Senate Internal Security Subcommittee and the House Un-American Activities Committee several times, but refused to answer most questions, citing the First and Fifth amendments. He joined Alfred A. Knopf in 1959 after the national anti-Communist fervor died down.
