Free and competitive international trade found one of its most outspoken advocates in Gottfried von Haberler. As Professor of Economics at Harvard University from 1936 until his retirement in 1971, Haberler argued tirelessly against the restrictive economic policies advocated by many of his colleagues -- arguments that were influenced by his study in the 1920s and 1930s with Ludwig von Mises in Austria.

His published books show a life-long interest in trade and business cycles -- The Theory of International Trade, Prosperity and Depression, and Economic Growth and Stability among them.

After retiring from Harvard University he became a Resident Scholar at the American Enterprise Institute in Washington, D.C.
