Born on this day 105 years ago, free-market economist Milton Friedman (1912-2006) was one of a kind.
Even the dyspeptic Paul Krugman called his rival "the economist's economist...a very great man indeed--a man of intellectual courage who was one of the most important economic thinkers of all time and possibly the most brilliant communicator of economic ideas to the general public that ever lived." The Economist (November 23, 2006) called him "the most influential economist of the second half of the twentieth century...and possibly all of it."
