Abstract
Jules Michelet remarked that the forms of association “must differ … among the different countries, according to the diversity of national genius.” and Denis W. Brogan once said (he is surely one who does not merit the reproach): “Because we have studied only France, we have not understood even France.” The second remark might apply to the United States, too. There has been talk of the value of comparative study of labor movements, but comparatively little application of comparative methods to labor history. A comparison of the history of association in labor unions in France and the United States may therefore throw a little more light on the “national genius” of each country as well as on die behavior of each labor movement.
