Virginia Postrel says it best in the above article:
One of my heroes, Milton Friedman, has died at 94. He was a great social scientist, a brilliant popularizer and polemicist, and a mensch. His intellectual influence, on both scholarly economics and the revival of classical liberalism, can hardly be overstated. And, more than any other single person, we can thank him for ending the scourges of the 1970s: inflation and the draft.
Dr. Friedman's book, Capitalism and Freedom, remains as one of the most influential books in my life. It was he who challenged the prevailing wisdom of the time, Keynesian economics (one of whose proponents, John Kenneth Galbraith, died earlier this year), and proved the fallacy of them. I was proud that he was the leading voice of the Chicago School of economics.
My cat Milton is named for him.
Rest in peace, Dr. Friedman. The world is better for having had you.
