Francis Lieber, who later held the first formal political science chair in America (Columbia, 1858), contrasted the English and French contributions to civil liberty in an article he published in 1849, the year following the European revolutions of 1848. Four years later, Lieber extended his analysis and added a major section on American liberty in Of Civil Liberty and Self-Government (1853). More than a century afterwards, Friedrich A. Hayek, who won the Nobel Prize for Economics in 1973, drew on Lieber's comparison of Anglican and Gallican Liberty in his treatise on political philosophy, The Constitution of Liberty (1960).
