This major expression of one of the leaders of the Chicago School, one of the most important schools of thought in contemporary American sociology, includes his recognized masterpieces of sociological research and writing. Hughes pioneered studies in a variety of sociological subjects: social institutions, racial interaction, work and occupations, and research methodology. Cumulatively, these essays show the obvious magnitude and scope of thought of one of the century's most distinguished scholars.In their introduction to this edition, Riesman and Becker provide a biographical background to Hughes' writing, describing his pervading influence on the field of sociology and on younger sociologists through his teaching, fieldwork, work in professional associations, and personality. The essays are grouped into four sections: the relationship of social institutions to changes in their surroundings and to the personalities and careers of persons; problems of multi-ethnic societies; the development of occupations, the monopoly license of professions, the determination of public policy about a line of work, and the relations between work and social role; and social observation and analysis.
