The 1982 IHS seminar I attended
It was a week long, in Hartford, CT, sponsored by the Institute for Humane Studies. The four faculty were:
Robert Nozick
Israel Kirzner
John Gray
Ronald Max Hartwell
Those were the only faculty, for one week — pretty amazing! Libertarianism and classical liberalism quite simply had much higher intellectual status in those days. You could not assemble a comparable group of lecturers today.
I thank David Price for jogging my memory here.
