Hazlitt, Henry (ed.). The Critics of Keynesian Economics. Princeton, New Jersey: Van Nostrand, 1960.
From the Mises Institute:
Henry Hazlitt confronted the rise of Keynesianism in his day and put together an intellectual arsenal: the most brilliant economists of the time showing what is wrong with the system, in great detail with great rigor. With excerpts from books and articles published between the 30s and 50s, it remains the most powerful anti-Keynesian collection ever assembled.
