Gaskell: "Few of the men who entered the trade rich were successful. They trusted too much to others, too little to themselves." Let us recall here that the founder of the largest industrial establishments of Belgium, John Cockerill, was a simple workman. See E. Mahaim, "Les Débuts de l'Établissement John Cockerill à Seraing", _Vierteljahrschrift für Social- und Wirtschaftsgeschichte_ (1905), p. 627.
