Two items of note:
1. Ross Emmett's EH.Net review of The Great Persuasion: Reinventing Free Markets since the Depression by Angus Burgin (Harvard, 2012), which focuses extensively on Hayek and the Mont Pèlerin Society. Ross calls it "a subtle and nuanced history," much better than recent similar books by Stedman Jones (2012) and Mirowski and Plehwe (2009).
2. A piece in National Affairs on Irving Kristol and Gertrude Himmelfarb which discusses Himmelfarb's interactions with Hayek in London in the 1930s (HT: Nicolai Foss). "Himmelfarb and Hayek discussed, among other intellectual topics, his forthcoming launch of 'an international Acton Society to promote the ideals of liberty and morality,' which became the Mont Pelerin Society. . . . Himmelfarb admired Hayek for having linked Acton to Adam Smith and the 'Manchester school.' . . . [S]he recapped Hayek's 1945 lecture at University College Dublin, in which he differentiated between the 'true individualists' of the Anglo-Scottish Enlightenment and the 'false individualists' of the Continental Enlightenment. . . . This sharp distinction between the two Enlightenments would later prove fundamental to both Himmelfarb's and Kristol's own work."
