Editing Friedrich Hayek (section)

=== Freiburg and Salzburg ===
From 1962 until his retirement in 1968, he was a professor at the [[Albert Ludwigs University of Freiburg|University of Freiburg]], West Germany, where he began work on his next book, ''[[Law, Legislation and Liberty]]''. Hayek regarded his years at Freiburg as "very fruitful".<ref>Ebenstein, p. 218.</ref> Following his retirement, Hayek spent a year as a visiting professor of philosophy at the [[University of California, Los Angeles]], where he continued work on ''Law, Legislation and Liberty'', teaching a graduate seminar by the same name and another on the philosophy of social science.<ref name=":8" /> Preliminary drafts of the book were completed by 1970, but Hayek chose to rework his drafts and finally brought the book to publication in three volumes in 1973, 1976 and 1979.<ref name=":12" />

Hayek became a professor at the [[University of Salzburg]] from 1969 to 1977 and then returned to Freiburg.<ref name=":3" /> When Hayek left Salzburg in 1977, he wrote: "I made a mistake in moving to Salzburg". The economics department was small, and the library facilities were inadequate.<ref>Ebenstein, p. 254.</ref>

Although Hayek's health suffered, and he fell into a depressionary bout, he continued to work on his [[Masterpiece|magnum opus]], ''[[Law, Legislation and Liberty]]'' in periods when he was feeling better.{{sfn|Ebenstein|2001|pp=251–53}}
