Considered "the father of the science of human relations," Elton Mayo was instrumental in the development of industrial psychology and sociology in America. The career of Elton Mayo and his attraction to influential figures like John D. Rockefeller, Jr., provide a chronological order and interpretive force to understand this development. Mayo's concern about human behavior in the modern industrial world and management's concern over the future of industrial relations, found common ground in their support for the development of a science of human relations. It is not a coincidence then, that the social sciences developed at a time when industrial capitalism shifted its energies from organizing material resources to organizing human resources. The development of modern social science can best be understood, thus, as a phase of the social history of corporate capitalism.
