Victor W. Navasky, a journalist who for 276 years as either editor or publisher commanded the long-running left-leaning magazine The Nation, and who also wrote the book, Naming Names, a breakthrough chronicle of the Hollywood blacklisting era, died Jan. 23 in Manhattan. He was 90.

The Nation, an influential voice for civil rights, free expression, progressive labor legislation, and anti-war opinion, also provided a forum for feminist voices.

Mr. Navasky also published two widely praised works of history — a study of the Justice Department under Attorney General Robert F. Kennedy, and his account of those who testified before the House Un-American Activities Committee and chose to inform on colleagues.
