Clarence S. Stein, renowned architect and city planner, began his career in the office of Bertram G. Goodhue. His first projects included a world exposition in San Diego and a copper-mining town in Tyrone, New Mexico. This work indicates that the Panama California Exposition of 1915 resulted in the commission of the company town in Tyrone, New Mexico and delineates the history behind this occurrence. In addition this work divulges the involvement of Clarence S. Stein on these two projects and suggests their influence, as well as the influence of Goodhue, over Stein?s later career.
