Who of the following is considered to be one of the intellectual godfathers of neo-liberal capitalism ?

Friedrich August von Hayek (author of The Road to Serfdom, 1944, and The Constitution of Liberty, 1960) is widely regarded as one of the principal intellectual godfathers of free-market neo-liberal capitalism for his defence of spontaneous market order and critique of state planning. John Rawls advanced welfare-state egalitarian liberalism, whereas Alasdair MacIntyre and Michael Walzer are associated with communitarianism.
