In 1950, Hayek left the London School of Economics for the University of Chicago, where he became a professor in the Committee on Social Thought. Hayek's salary was funded not by the university, but by an outside foundation. University of Chicago President Robert Hutchins was in the midst of a war with the U. of Chicago faculty over departmental autonomy and control, and Hayek got caught in the middle of that battle. Hutchins had been attempting to force all departments to adopt the neo-Thomist Great Books program of Mortimer Adler, and the U. of Chicago economists were sick of Hutchins' meddling. As the result the Economics department rejected Hutchins' pressure to hire Hayek, and Hayek became a part of the new Committee on Social Thought.
Why did the economics department turn down Hayek's employment?
****
The answer:
sick of Hutchins' meddling
