“ That Detroit ultimately concentrated on automobiles could be traced to one genius, Henry Ford.... But that the necessary human energy for this development existed in Detroit could be proven through its early history.... I told him what I knew of the settlement in Detroit and of the climate, certainly almost the worst in the United States. Only the very strong could survive.... To defeat the conditions imposed by earth and sky at Detroit required intensive labor by energetic men who were not tempted by pleasure and play. ”
