The advent of the industrial revolution brought technologies based on coal, iron, canals, and railroads, but the Dutch, unversed in English, and lacking connections to the English-speaking establishment, were unable to engage in entrepreneurship on a large scale. Consequently, the large-scale enterprises which came to characterize the industrialized eastern half of the region, such as the Lehigh Coal and Navigation Company (marketer of the coal branded "Old Company's Lehigh"), the Lehigh Valley Railroad, and the Bethlehem Iron Company (later known as Bethlehem Steel) were founded by English speaking residents from the Philadelphia and New York areas. The English-speakers (referred to by the Dutch as simply "the English") dominated the managerial and engineering positions of these companies, and the Dutch supplied the blue collar and supervisory workforce.
