Question: Melbourne has the largest tram network in the world which had its origins in the city's 1880s land boom. In 2013–2014, 176.9 million passenger trips were made by tram. Melbourne's is Australia's only tram network to comprise more than a single line and consists of 250 km (155.3 mi) of track, 487 trams, 25 routes, and 1,763 tram stops.

Question: 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.
Is there an answer to this question: Who supplied Hayek's salary?

Answer:
an outside foundation
