This work is a four-part history of the development of architecture as a profession in the United States. Section One covers the beginnings in Colonial times when there were no identifiable professionals. Section Two examines architecture from 1800 to the Civil War, a period during which the first architects appeared. Section Three considers the profession from the time of the Civil War to World War I and the strengthening of the profession's status. Section Four covers architecture since World War I. Each section discusses the training of architects, standards of practice, general management methods, information sources, minority participation, and other aspects of professional operation, with special attention given to the relationship between the profession's development and the social history of the periods.
