John Rensselaer Chamberlain (October 28, 1903 – April 9, 1995) was an American journalist, business and economic historian, syndicated columnist, and literary critic who was dubbed "one of America's most trusted book reviewers" by the libertarian magazine The Freeman.
In 1939, Chamberlain was among the "editorial sponsors" of the Writer's Anti-War Bureau that was formed by an informal group of journalists and publicists under the leadership of America First Committee publicity director Sidney Hertzberg.
The Bureau publicized a weekly newssheet entitled Uncensored, which worked to analyze the news, expose the propaganda and hidden biases of those who advocated for foreign intervention.
[9] Influenced by Albert Jay Nock, he credits the writers Ayn Rand, Isabel Paterson and Rose Wilder Lane with his final "conversion" to what he called "an older American philosophy" of libertarian and conservative ideas.
[10] Along with his friends Henry Hazlitt and Max Eastman, he helped to promote the work of the Austrian economist F. A. Hayek, The Road to Serfdom, writing the "Foreword" to the first American edition of the book in 1944.
